| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: prevent potential lcn remains uninitialized
The target VCN being sought was not found within runs[0], causing
run_lookup() to return false. This causes run_lookup_entry() to return
false, which in turn results in a len value of 0, and the new parameter
passed to attr_data_get_block() is NULL. Collectively, these factors
ultimately cause attr_data_get_block_locked() to exit prematurely without
initializing lcn, thereby triggering [1].
To prevent [1], the clen check within ni_seek_data_or_hole() has been
moved to occur before the lcn check.

| In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: Decouple req recycling from RPC completion
rl_kref formerly served two distinct lifetimes through a single
refcount: it gated when a Reply could wake its RPC task, and it
gated when an rpcrdma_req could return to its free pool. The
marshal path took the Send-side reference only when SGEs needed
DMA-unmap (sc_unmap_count > 0), which made a Send carrying only
pre-registered buffers an exception: the Reply handler dropped
rl_kref from 1 to 0 and freed the req while the HCA might still
be DMA-reading from its send buffer.
Give rl_kref a narrower job. The RPC layer takes one reference
when slot allocation hands a req out. rpcrdma_prepare_send_sges()
takes a Send-side reference unconditionally after WR preparation
succeeds. xprt_rdma_free_slot() and xprt_rdma_bc_free_rqst() drop
the RPC-layer reference; rpcrdma_sendctx_unmap() drops the
Send-side reference. The req returns to its free pool only after
both owners have signed off.
The existing kref_init(&req->rl_kref) call in
rpcrdma_prepare_send_sges() is removed. Initialization moves to
the slot-allocation paths (xprt_rdma_alloc_slot and
rpcrdma_bc_rqst_get), and the release callback re-arms rl_kref
before the req returns to a free pool. A re-init in the marshal
path would discard the RPC-layer reference that already exists
on entry.
Three invariants follow:
- Any rpcrdma_req held by an rpc_rqst has rl_kref >= 1.
xprt_rdma_alloc_slot(), rpcrdma_bc_rqst_get(), and the
backlog-wake branch in xprt_rdma_alloc_slot() each kref_init
rl_kref before publishing the req. Without this invariant,
an RPC task that aborts between slot allocation and marshal
(gss_refresh failure or signal during call_connect, for
example) would drive xprt_release() ->
xprt_rdma_free_slot() -> kref_put against a refcount of
zero, saturating refcount_t and stranding the slot.
- The Send-side reference is taken only after WR prep
succeeds. A mapping failure in rpcrdma_prepare_send_sges()
runs rpcrdma_sendctx_cancel(), which DMA-unmaps the sendctx
and clears sc_req without touching rl_kref. The sendctx
ring walks in rpcrdma_sendctx_put_locked() and
rpcrdma_sendctxs_destroy() skip entries with sc_req == NULL,
so a burst of -EIO marshal failures cannot hold reqs off
rb_send_bufs.
- The release callback re-arms rl_kref so the next consumer
enters with the invariant satisfied.
Replies now complete the RPC directly. rpcrdma_reply_handler()
calls rpcrdma_complete_rqst() in place of kref_put on the
non-LocalInv branch. The LocalInv branch already completes the
RPC from frwr_unmap_async() and is unaffected.
Because Send-side references can now outlive RPC completion,
connection teardown drains sendctx entries whose unsignaled
Sends never had a later signaled completion to walk the ring.
rpcrdma_sendctxs_destroy() walks the active range and runs
rpcrdma_sendctx_unmap() on each entry with a non-NULL sc_req
before the request buffers are reset, and is moved ahead of
rpcrdma_reqs_reset() in rpcrdma_xprt_disconnect() so the reqs
are still in their pre-reset state when the Send-side refs are
released.
The drain creates a teardown-ordering hazard on the backchannel
path. With the new lifetime, releasing a bc_prealloc req from
rpcrdma_req_release() re-adds it to bc_pa_list. The disconnect
in xprt_rdma_destroy() runs after xprt_destroy_backchannel() has
already emptied bc_pa_list, so the drained reqs would otherwise
leak. xprt_rdma_destroy() now runs xprt_rdma_bc_destroy(xprt, 0)
a second time after the disconnect to reclaim them. |
| In the Linux kernel, the following vulnerability has been resolved:
gpib: fix double decrement of descriptor_busy in command_ioctl()
commit d1857f8296dc ("gpib: fix use-after-free in IO ioctl handlers")
introduced a descriptor_busy reference counter to pin struct
gpib_descriptor across IO ioctl operations. In command_ioctl(), the
error path inside the loop decrements descriptor_busy and breaks, but
execution then falls through to the unconditional decrement after the
loop, underflowing the counter to -1.
This re-enables the use-after-free that the original fix was meant to
prevent: a concurrent close_dev_ioctl() sees descriptor_busy == 0 on
an actively-used descriptor and frees it.
Remove the early decrement from the error path. The post-loop
decrement already handles all exit paths, matching the correct pattern
used in read_ioctl() and write_ioctl(). |
| In the Linux kernel, the following vulnerability has been resolved:
net: mpls: initialize rtm_tos in mpls_getroute()
mpls_getroute() builds the RTM_NEWROUTE reply to an RTM_GETROUTE
request by filling a struct rtmsg allocated from an skb whose data
area is not zeroed (alloc_skb(NLMSG_GOODSIZE, ...)). It sets every
field of the header except rtm_tos:
r = nlmsg_data(nlh);
r->rtm_family = AF_MPLS;
r->rtm_dst_len = 20;
r->rtm_src_len = 0;
r->rtm_table = RT_TABLE_MAIN;
r->rtm_type = RTN_UNICAST;
r->rtm_scope = RT_SCOPE_UNIVERSE;
r->rtm_protocol = rt->rt_protocol;
r->rtm_flags = 0;
struct rtmsg has no padding, so the one uninitialised byte rtm_tos
(offset 3) is copied straight to user space on recvmsg(), leaking a
byte of uninitialised heap memory. This is in contrast to
mpls_dump_route(), which fills the very same header and does set
rtm_tos = 0.
Initialize rtm_tos to 0, matching mpls_dump_route().
Reproduced with KMSAN by adding an MPLS route and issuing a
non-RTM_F_FIB_MATCH RTM_GETROUTE for its label:

| In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Allow entries in BO caches to be freed
When a buffer object is pinned via host1x_bo_pin() with a cache, the
resulting mapping is kept in the cache so it can be reused on subsequent
pins. Each mapping held a reference to the underlying host1x_bo (taken
in tegra_bo_pin / gather_bo_pin), so as long as a mapping was cached,
the bo itself could not be freed.
However, the only way to remove the cached mapping was through the free
path of the buffer object. This meant that if a bo got cached, it could
never get freed again.
Resolve the circularity by holding a weak reference to the bo from the
cache side. This is done by having the .pin callbacks not bump the bo's
refcount -- instead the common Host1x bo code does so, except for the
cache reference.
Also move the remove-cache-mapping-on-free code into a common function
inside Host1x code. This is only called from the TegraDRM GEM buffers
since those are the only ones that can be cached at the moment. |
| In the Linux kernel, the following vulnerability has been resolved:
raid1: fix nr_pending leak in REQ_ATOMIC bad-block error path
In raid1_write_request(), each per-mirror loop iteration begins by
incrementing rdev->nr_pending. If a REQ_ATOMIC write encounters a
badblock within the requested range, the code jumps to err_handle
without dropping the reference taken for the current mirror.
err_handle's cleanup loop will only decrements for k < i and
r1_bio->bios[k] is non-NULL. The current slot is therefore skipped,
leaving its nr_pending reference leaked permanently. The reference
prevents the rdev from ever being removed, since raid1_remove_conf()
refuses to remove an rdev with nr_pending > 0.
Fix this by calling rdev_dec_pending() before jumping to err_handle. |
| In the Linux kernel, the following vulnerability has been resolved:
liveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish()
In luo_file_unpreserve_files() and luo_file_finish(), reorder
module_put() and xa_erase() to ensure the file handler module remains
pinned while its operations are being accessed.
Specifically, luo_get_id() dereferences fh->ops->get_id, so the module
reference must be held until after xa_erase() (which calls luo_get_id)
completes.
For luo_file_finish(), this requires moving the module_put() call out of
the luo_file_finish_one() helper and into the main loop of
luo_file_finish() itself. |
| CKAN MCP Server is a tool for querying CKAN open data portals. A known vulnerability CVE-2026-33060 indicated tools including ckan_package_search and sparql_query that accept a base_url parameter had the risk of making HTTP requests to arbitrary endpoints without restriction. A fix was applied to filter out ip addresses. However, a method to bypass exists prior to version 0.4.106. CKAN MCP Server validates caller-supplied CKAN server URLs by inspecting only the parsed hostname string before issuing outbound HTTP requests. In `src/utils/http.ts`, hostname aliases such as `ip6-localhost` are not equal to `localhost`, are not dotted IPv4 literals, and are not bracketed IPv6 literals, so they pass the SSRF filter but can resolve to loopback when the server performs the request. A remote MCP caller that can invoke CKAN tools with a `server_url` can therefore make the server connect to local or private addresses and, for CKAN-shaped responses, receive response-derived data. The updated fix in version 0.4.106 replaced the single `hostname === 'localhost'` check with a blocked-hostname `Set` covering `ip6-localhost` and `ip6-loopback`. |
| Orval generates type-safe JavaScript clients in TypeScript from OpenAPI v3 and Swagger v2 specifications. Prior to 8.21.0, a ${...} expression or backtick in a header parameter default is emitted into a module-level template literal emitted by zod schema generation without safe encoding. This permits attacker-controlled JavaScript to be evaluated when the generated zod schema module is imported, resulting in code execution in the developer, CI, test, or application environment. The affected code is packages/zod/src/index.ts function formatDefaultValue. This issue is fixed in version 8.21.0. |

| Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has a use-after-free in buffer.c when evbuffer_add_buffer_reference processes an output buffer whose out_total_len is zero. evbuffer_free_all_chains frees the initial empty chain without resetting outbuf->first, outbuf->last, or outbuf->last_with_datap, and APPEND_CHAIN_MULTICAST subsequently dereferences the dangling chain pointer. A caller that can drive this buffer state can cause memory corruption or a process crash. This issue is fixed in versions 2.1.13 and 2.2.2-alpha. |

rxrpc: Fix leak of released call in recvmsg(MSG_PEEK)
Fix rxrpc_recvmsg() to also drop the ref it holds on an already-released
call if MSG_PEEK is in force (the function holds a ref on the call
irrespective of whether MSG_PEEK is specified or not). |
| In the Linux kernel, the following vulnerability has been resolved:
binfmt_misc: don't let an 'F' entry pin its own instance
An entry registered with 'F' opens its interpreter at registration time
and holds that file until the entry is freed. Any entry nobody removes
by hand only gets closed once the binfmt_misc superblock is shut down.
If the interpreter lives on a mount that keeps that superblock alive the
two pin each other:
binfmt_misc sb -> inode -> entry -> interp_file -> vfsmount -> binfmt_misc sb
TL;DR the file is never closed. Once the mount namespace is gone there
is nothing left to unregister through either.
There are two ways to trigger this bug:
- Point the interpreter at the instance itself. Its files are regular
files owned by the mounter and both bm_get_inode() and
simple_fill_super() leave i_op at empty_iops. So notify_change() falls
back to simple_setattr() and chmod +x works. We never set SB_I_NOEXEC
and so open_exec() accepts it.
- Use the instance as an overlayfs lower layer. The overlay superblock
holds a clone_private_mount() of every layer until it is destroyed and
that clone is in no namespace. So umount_tree() never reaches it.
That's a DoS. And it isn't only the superblock that leaks. It pins the
user namespace it was mounted in, so every iteration permanently eats
one of the caller's user namespace charges.
So let's just do the sane thing. SB_I_NOEXEC makes open_exec() fail on
the instance's own files and s_stack_depth makes overlayfs reject the
layer before it ever takes a clone. That also covers the ecryptfs and
fuse passthrough variants. What 'F' promises is unchanged.
The stable tag is narrower than the Fixes tags on purpose. Before
sandboxed mounts this needed global root against the single instance
everyone shares, and the change doesn't apply to those trees anyway.
Note that SB_I_NODEV is implicitly raised for userns mounts but raise it
explicitly here as well. |
| An issue in Halo 2.25.4 allows a remote attacker to execute arbitrary code via the PluginEndpoint.java, installFromUri method, and DefaultPluginApplicationContextFactory components |
| SiYuan before v3.7.4 contains a server-side request forgery (SSRF) vulnerability in the isPrivateIP function in kernel/util/net.go, used by SSRFSafeDialer to enforce SSRF protection in SafeMode. The function only checks for loopback, link-local unicast, private, and unspecified addresses and does not recognize IPv6 transition addresses (NAT64 64:ff9b::/96, 6to4 2002::/16, Teredo 2001::/32) that embed private IPv4 destinations. When SafeMode is enabled, an authenticated attacker can bypass the SSRF guard via the network forward proxy, WebSocket proxy, or SSE proxy endpoints by supplying a URL whose hostname resolves to such a transition address, reaching internal services and cloud metadata endpoints (e.g., 169.254.169.254). Because the forward proxy returns the full response body, this is a full-read SSRF that can be used to steal instance credentials, reach internal services, and port-scan internal infrastructure. |
| Oh My Zsh is a community-driven framework for managing Zsh configuration. Prior to 2026-05-28, the dotenv plugin in plugins/dotenv/dotenv.plugin.zsh passes ZSH_DOTENV_FILE to source after a directory change into a folder containing a .env file, allowing syntactically valid shell commands in the file to execute with the current account's privileges, including without a prompt when ZSH_DOTENV_PROMPT=false or after the default prompt accepts an empty Enter response. This issue is fixed in versions released after 2026-05-28. |
| Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. Prior to 0.3.0, multipart POST /v1/sessions accepts an authenticated user's agent bundle and omnigent/server/bundles.py validate_agent_bundle does not reject a tools..callable dotted Python path. omnigent/runner/tool_dispatch.py _resolve_spec_callable imports the specified module and _execute_spec_callable_tool invokes the resolved function, allowing a bundle to select subprocess.check_output and execute a local command with the runner process permissions. This can expose runner files, environment variables, credentials, workspace data, internal services, and availability without administrator access. This issue is fixed in version 0.3.0. |
| Unleash is an open-source feature management platform. Prior to 7.5.2, 7.6.5, and 8.0.2, the addon and integration subsystem passes the operator-controlled parameters.url value from src/lib/addons/webhook.ts and the Slack, Microsoft Teams, Datadog, and New Relic integrations to Addon.fetchRetry in src/lib/addons/addon.ts without restricting loopback, link-local, private, or cloud metadata addresses. An authenticated actor with the root CREATE_ADDON or UPDATE_ADDON permission can cause the server to send requests from inside its network boundary, use integration event status as a blind probing oracle, forward Authorization, customHeaders, or DD-API-KEY values to an attacker-observed host, and deliver the feature-event JSON body to internal services. This issue is fixed in versions 7.5.2, 7.6.5, and 8.0.2. |
| SpecifyJS is a declarative TypeScript user interface framework. Prior to version 0.2.136, when `new URL()` throws a parse error, the `assertSecureUrl` function returned without throwing, silently allowing the request to proceed without HTTPS validation. Starting in version 0.2.136, the catch block now throws an error instead of silently returning. |
| MobSF is a mobile application security testing tool used. Prior to 4.5.1, get_browsable_activities in mobsf/StaticAnalyzer/views/android/manifest_analysis.py validates only an Android manifest android:host value with valid_host before appending a separately supplied android:port to the URL fetched by _check_url, allowing an authenticated user to upload a crafted APK that makes requests to an attacker-selected nonstandard port at /.well-known/assetlinks.json. With an attacker-controlled hostname and DNS rebinding between validation and the requests.get connection, the request can reach an internal service, although redirects remain disabled and the path is fixed. This issue is fixed in version 4.5.1. |
