| Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache Calcite Avatica. Plugin instantiation (via AvaticaUtils#instantiatePlugin and other methods) initializes arbitrary classes via unrestricted calls to Class.forName(String) which by default triggers initialization. This may lead to the execution of static initializer blocks in arbitrary classes present in the classpath. The instantiation APIs should initialize and instantiate only classes implementing the specified plugin interface passed as input in conjunction with the desired classname. At the moment of writing, there are no well-known or widely used classes with dangerous static initializer blocks so the severity is low.
This issue affects Apache Calcite Avatica: before 1.29.0.
Users are recommended to upgrade to version 1.29.0, which fixes the issue. |
| A Null Pointer Dereference in the mk_sched_event_close function (mk_server/mk_scheduler.c) of Monkey through commit 4fb0c16 allows attackers to cause a Denial of Service (DoS) via sending a crafted HTTP request to the server. |
| A flaw has been found in Freedesktop Poppler 26.07.0. Impacted is the function JBIG2Stream::rewind of the file poppler/JBIG2Stream.cc. This manipulation causes null pointer dereference. It is possible to initiate the attack remotely. The exploit has been published and may be used. Upgrading to version 26.08.0 is recommended to address this issue. Patch name: 5e49250f13b0390edeb3f90eb4c02c9941f97067. Upgrading the affected component is advised. |
| Notepad++ is a free and open-source source code editor. Prior to 8.9.8, the NPPM_SAVESESSION handler in PowerEditor/src/NppBigSwitch.cpp converts lParam to a sessionInfo pointer and dereferences its nbFile, files, and sessionFilePathName members without checking for null. A process running at the same or a higher Windows integrity level on the same desktop can send NPPM_SAVESESSION with a null lParam, immediately terminating Notepad++ and causing denial of service and loss of unsaved documents. This issue is fixed in version 8.9.8. |
| Null pointer dereference in Windows Kerberos allows an unauthorized attacker to deny service over a network. |
| An account holding the nexus:settings:update permission in Nexus Repository 3 (or the equivalent nexus:settings permission in the legacy Nexus Repository 2) could submit arbitrary values as realm identifiers through an internal configuration API that did not validate them against the set of registered realms. Because unrecognized entries were persisted and re-evaluated on every realm load via a legacy code path, this could result in unintended code executing inside the Nexus Repository process, and in some cases a persistent authentication lockout that was not visible through the administrative UI. |
| A vulnerability was found in Open5GS up to 2.8.0. This affects the function ogs_pfcp_parse_volume_measurement in the library lib/pfcp/types.c of the component PFCP Handler. The manipulation results in null pointer dereference. The attack may be launched remotely. The patch is identified as 8f07b507b78ff94776f2cd49276eb116ed93d7f2. A patch should be applied to remediate this issue. |
| Null pointer dereference in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to deny service over a network. |
| A flaw was found in libxml2. A local user or an attacker providing a specially crafted XML catalog can trigger a NULL pointer dereference during XML catalog parsing. This occurs when a `nextCatalog` element lacks its mandatory `catalog` attribute, leading to the application crashing and causing a Denial of Service (DoS). |
| Null pointer dereference in Windows SMB Server Network Transport Driver (srvnet.sys) allows an unauthorized attacker to deny service over a network. |
| vm2 versions from 3.9.6 before 3.11.7 fail to properly restrict access to accessor properties on frozen objects, allowing sandboxed scripts to bypass vm.freeze() and vm.readonly() protections. Attackers can use Object.getOwnPropertyDescriptor() or __lookupSetter__() to extract and invoke host object setters directly, mutating properties the embedder explicitly marked read-only. |
| A security flaw has been discovered in GNU Binutils 2.47. This vulnerability affects the function elf_orphan_compatible of the file ld/ldelf.c of the component ELF Orphan Section Handler. Performing a manipulation results in null pointer dereference. The attack must be initiated from a local position. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through a bug report but has not responded yet. |
| The RestroPress WordPress plugin before 3.4.6 does not validate a client-supplied item add-on price on the server side when items are added to or updated in the cart, allowing unauthenticated users to set an arbitrary price and place orders for an attacker-chosen total, down to and including zero. |
| A NULL pointer dereference flaw was found in GStreamer's RTSP support library. The vulnerability occurs while parsing an Authorization or WWW-Authenticate header that uses Digest authentication. Specially crafted whitespace placement around a parameter's terminator can cause an internal length calculation to underflow, leading to a crash of the process parsing the header. On an RTSP server this can be triggered by a remote, unauthenticated attacker sending a single malformed request when the server has authentication enabled; the same flaw can also be triggered against an RTSP client by a malicious or compromised RTSP server. Successful exploitation results in a denial of service (application crash) and has no confirmed impact on confidentiality or integrity. |
| MISP contains an insecure direct object reference vulnerability in the processModuleResultsData method of the Event model. When processing module results, the code iterates over EventReport entries supplied in the resolved data and saves each one. Unlike the adjacent attribute and object processing loops, the report loop did not unset the client-supplied 'id' field before calling save(). Because the MISP EventReport model's create() method does not strip the id field, an authenticated user with permission to submit module results could include an 'id' value referencing an existing report belonging to a different event. Upon save(), the ORM would update that existing row rather than insert a new one, allowing the attacker to
- read the content of another event's report by reparenting it into their own event
- overwrite the report's fields with attacker-controlled data
- change the report's event_id to redirect ownership.
This constitutes an authorization bypass through a user-controlled key, enabling cross-event data disclosure and integrity compromise. The vulnerability requires an authenticated session with the ability to invoke module result processing on an event.

| In the Linux kernel, the following vulnerability has been resolved:
iommu/tegra241-cmdqv: Publish an LVCMDQ only after it is fully initialized
tegra241_vintf_init_lvcmdq() stores the freshly allocated vcmdq pointer to
the vintf->lvcmdqs[] array, before tegra241_vcmdq_alloc_smmu_cmdq() builds
the vcmdq->cmdq. The error ISR dereferences that cmdq, so a latched LVCMDQ
error (e.g. one inherited across a kexec) firing in this window would make
tegra241_vintf0_handle_error() pass the still-zeroed arm_smmu_cmdq down to
__arm_smmu_cmdq_skip_err(), dereferencing NULL queue register pointers.
Drop the store from tegra241_vintf_init_lvcmdq() and publish the vcmdq at
the end of the allocation instead, with an smp_store_release() that pairs
with an smp_load_acquire() in the ISR, which can see a fully built LVCMDQ
or NULL.
The user-owned LVCMDQ allocation moves accordingly, publishing the vcmdq
once tegra241_vcmdq_hw_init_user() succeeds, using a plain store since a
user VINTF's lvcmdqs[] has no lockless reader -- the error ISR only walks
the VINTF0 array. |
| In the Linux kernel, the following vulnerability has been resolved:
NFSD: Guard admin state-revocation walks with NFSD_NET_UP
Writing to /proc/fs/nfsd/unlock_filesystem, or sending the
NFSD_CMD_UNLOCK_FILESYSTEM or NFSD_CMD_UNLOCK_EXPORT netlink command,
walks the NFSv4 client hash tables to revoke open state and cancel
async COPY operations. All three handlers gate that walk on
nn->nfsd_serv, but a listener added via portlist or netlink
listener_set sets nn->nfsd_serv before any nfsd thread starts.
nfsd_startup_net() has not yet allocated nn->conf_id_hashtbl, so the
walkers dereference a NULL table. A local administrator with
CAP_SYS_ADMIN can crash the kernel this way without ever starting the
server.
nn->nfsd_serv is set when the service is created, which precedes
table allocation. NFSD_NET_UP instead brackets the window where the
tables are live: set at the end of nfsd_startup_net() and cleared in
nfsd_shutdown_net() after they are freed, both under nfsd_mutex.
Gating the three unlock paths on NFSD_NET_UP fixes the startup-time
NULL dereference while preserving the earlier post-shutdown
use-after-free fix. |
| In the Linux kernel, the following vulnerability has been resolved:
rpcrdma: arm rn_done before publishing the notification
rpcrdma_rn_register() inserts @rn into rd_xa with xa_alloc() before
storing the caller's callback in rn->rn_done. The xarray makes @rn
reachable to rpcrdma_remove_one(), which walks rd_xa and invokes
rn->rn_done(rn) for every registered notification. A device removal
that races a fresh registration can therefore observe @rn with
rn_done still NULL, because the notification objects are zero
allocated by their owners, and call through a NULL function pointer.
Store rn->rn_done before xa_alloc() publishes @rn. The xarray's
store-side and load-side ordering then guarantees that any CPU which
finds @rn in rd_xa also observes the armed callback.
rpcrdma_rn_unregister() treats a non-NULL rn_done as the sentinel
for a completed registration, so the early store must not survive a
failed registration. Clear rn_done again when xa_alloc() fails.
Were it left set, the failed-accept cleanup path would call
rpcrdma_rn_unregister() on an @rn that was never inserted, erasing
an unrelated rd_xa slot and underflowing rd_kref. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject redirect helpers without a bpf_net_context
The bpf_redirect*() helpers and skb_do_redirect() obtain the per-task
bpf_redirect_info via bpf_net_ctx_get_ri(), which dereferences the
current->bpf_net_context unconditionally. That context is established
on the paths that run tc BPF such as sch_handle_{ingress,egress}(),
*except* for the case where {cls,act}_bpf was attached to a proper
qdisc. A program running from there reaches the NULL deref in two ways:
* It calls bpf_redirect() directly, which dereferences the context at
the top of the helper:
tc qdisc add dev eth0 root handle 1: red limit 1MB min 10KB max 20KB \
avpkt 1000 burst 100 qevent early_drop block 10
tc filter add block 10 pref 1 bpf obj redirect.o
* It simply returns TC_ACT_REDIRECT without helper call: tcf_qevent_handle()
then dispatches to skb_do_redirect(), which dereferences the context
Rather than extending bpf_net_context management into the qdisc path,
make the redirect helpers refuse to operate when no context exists, and
have tcf_qevent_handle() drop a TC_ACT_REDIRECT verdict instead of
calling skb_do_redirect(). Previous behaviour was a crash, so nothing
regresses by not supporting it. |
