| Vulnerability in Oracle Essbase (component: Federated Partitions). The supported version that is affected is 21.8.3.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Essbase. While the vulnerability is in Oracle Essbase, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Essbase accessible data as well as unauthorized update, insert or delete access to some of Oracle Essbase accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Essbase. CVSS 3.1 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L). |

| Isar is an integration system for automated root filesystem generation. In versions 0.11 and newer, /etc/apt/trusted.gpg.d is created manually during bootstrap setup to be able to deploy local keys. By that, the directory is owned by the calling user (the one that executes Isar) instead of root. If the calling user's id is identical to one of an unprivileged user inside the image, this user is able to alter existing keys and deploy new ones, silently breaking the apt repo integrity protection. The issue is has no impact on those images that use an immutable rootfs, or if apt is never invoked. Changing only the keys does not trigger an exploit, it's just one step in a chain. An attacker would also have to manipulate a remote repo or intercept non-secure communication with it. This issue has been patched via commit 29e84ed. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: codecs: max98363: fix uninitialized stream_config->type
stream_config is not initialized before being passed to
sdw_stream_add_slave(). The type field may contain garbage and is
later copied to stream->type by sdw_config_stream().
Zero-initialize stream_config so type defaults to SDW_STREAM_PCM. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64/fpsimd: signal: Forbid non-streaming SVE payload on SME-only systems
When system_supports_sme() is true but system_supports_sve() is false,
restoring a specifically crafted SVE signal context can result in the
task erroneously having non-streaming SVE state. Subsequent attempts to
manipulate the task's FPSIMD/SVE/SME state can result in a variety of
problems, including fatal EL1 UNDEFs.
In such configurations, the kernel always creates an SVE signal context
when delivering a signal, and this can only be in one of two states:
(1) SVE_SIG_FLAG_SM is set, and an SVE payload is present containing
streaming mode SVE state. The recorded VL is the task's live
streaming VL.
(2) SVE_SIG_FLAG_SM is clear, and an SVE payload is not present. The
FPSIMD context contains the non-streaming mode FPSIMD state. The
recorded VL is 0.
Currently restore_sve_fpsimd_context() correctly rejects cases where
SVE_SIG_FLAG_SM is set and an SVE payload is not present, but fails to
reject cases where SVE_SIG_FLAG_SM is clear and an SVE payload is
present. Consequently, restore_sve_fpsimd_context() can place the task
in a state where it has non-streaming SVE state even when this is not
supported by HW.
For example, this can cause a later EL1 UNDEF when the kernel attempts to
restore the task's ZCR_EL1 value:

Rework restore_sve_fpsimd_context() to reject cases where
SVE_SIG_FLAG_SM is clear and an SVE payload is not present. As
parse_user_sigframe() rejects SVE signal frames when neither SVE nor SME
are supported, it isn't necessary for restore_sve_fpsimd_context() to
handle the case where neither are supported. |
| In the Linux kernel, the following vulnerability has been resolved:
serial: ma35d1: Fix clock reference leak in ma35d1serial_probe()
of_clk_get() returns a clock with a reference that has to be released
with clk_put(). ma35d1serial_probe() never does that, so the reference
is leaked on the probe error paths and also when the port is removed.
Release it on the error paths and in ma35d1serial_remove(). |

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: remove stale channels from all sessions on teardown
ksmbd_sessions_deregister() removes a connection's channels from other
sessions' channel lists only while conn->binding is still set:
if (conn->binding) {
hash_for_each_safe(sessions_table, ...)
ksmbd_chann_del(conn, sess);
}
conn->binding is a transient flag: it is cleared once a binding
SESSION_SETUP completes, and also by a subsequent non-binding
SESSION_SETUP on the same connection (a reauthentication on a bound
channel, or a new SessionId==0 setup). A connection that has bound a
channel into another session's ksmbd_chann_list and then clears
conn->binding leaves that channel behind when it disconnects: the
channel, whose chann->conn points at the now freed struct ksmbd_conn,
stays on the owner session's list.
When the owning connection later tears down, the second loop
dereferences the stale channel:
xa_for_each(&sess->ksmbd_chann_list, chann_id, chann)
if (chann->conn != conn)
ksmbd_conn_set_exiting(chann->conn); /* freed */
which is a use-after-free write into the freed ksmbd_conn (the same
stale channel is also walked by show_proc_session() through /proc). The
session is leaked as well, because its channel list never empties.
Remove the conn->binding gate so a connection always removes its
channels from every session on teardown. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: ccp - Fix possible deadlock in SEV init failure path
__sev_platform_init_handle_init_ex_path() calls
rmp_mark_pages_firmware() with locked=false while the parent
function of init_ex_path already acquired the sev_cmd_mutex.
In the case of an RMPUPDATE failure for any page after the first, the cleanup
path would invoke reclaim pages which would result in a deadlock in
sev_do_cmd.
Pass locked=true to honor the lock status of the parent function. |
| In the Linux kernel, the following vulnerability has been resolved:
freevxfs: don't BUG() on unknown typed-extent type
vxfs_bmap_typed() handles four typed-extent types and calls BUG() in
its default case, so an on-disk typed extent with any other type value
crashes the kernel. It is reachable from ioctl(FIBMAP) on a regular
file:
kernel BUG at fs/freevxfs/vxfs_bmap.c:230!
RIP: vxfs_bmap_typed fs/freevxfs/vxfs_bmap.c:230 [inline]
vxfs_bmap1+0x128a/0x12d0 fs/freevxfs/vxfs_bmap.c:257
Replace the BUG() with WARN_ON_ONCE() and return 0 -- the value
vxfs_bmap_typed() already returns on failure (and from the DEV4 case
above); vxfs_getblk() maps 0 to -EIO, so the ioctl fails cleanly. |
| In the Linux kernel, the following vulnerability has been resolved:
host1x: bus: Fix missing ops null check in error teardown
In host1x_device_init(), the error teardown paths do not check
client->ops before dereferencing it, unlike the forward init paths
which correctly guard with 'client->ops &&'. This can result in a
NULL pointer dereference if client->ops is NULL.
Fix by adding the missing client->ops check in both the teardown
and teardown_late labels. |
| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v4: Don't advertise VLPIs if no ITS is probed
When accidentally setting “kvm-arm.vgic_v4_enable=1” on a system that has
no MSI controller device tree node and GICv4, it results a panic as
“gic_domain” is NULL and the kernel attempts to access it.

Set vLPI support to false at init time if the host has no ITS, so it

| In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v5: Immediately exec priority drop following activate
With GICv5 an interrupt of equal or lower priority cannot be signalled
until there has been a priority drop. This is done via the GIC CDEOI
system instruction. Once this has been executed, the hardware is able
to signal the next interrupt if there is one.
As all interrupts are programmed to have the same priority, no new
interrupts can be signalled until the priority drop has happened. This
can cause issues when, for example, an interrupt remains active while
a long running process takes place, such as when injecting a physical
interrupt into a guest VM in software.
The GICv5 driver has so far done the priority drop as part of
irq_eoi(), i.e., at the same time as deactivating the interrupt. This
means that any long running process (or VM) could block incoming
interrupts, effectively causing a denial of service for all other
interrupts.
Rather than doing the EOI as part of irq_eoi() (which the name would
suggest would be a good place for it), move it to happen immediately
after acknowledging an interrupt in the main GICv5 interrupt
handler. The deactivation of interrupts (GIC CDDI) remains implemented
as part of irq_eoi(), which means that the same interrupt cannot be
signalled a second time until deactivated by software. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs3: handle set_blocksize failures
ntfs3 uses buffer_heads, which don't handle block size > PAGE_SIZE well.
Without this, mounting we will hit the
BUG_ON(offset >= folio_size(folio));
in folio_set_bh on the first __bread_gfp call. |

media: chips-media: wave5: Add range checks for dec_output_info
If the driver's dec_output_info contains invalid data the driver can
write in invalid memory. Add a range check for that.
This fixes this smatch error:

| In the Linux kernel, the following vulnerability has been resolved:
ext4: don't enable large folios on encrypted inodes
Commit 709f0f1f1bf5 ("ext4: add checks for large folio
incompatibilities when BS > PS") disables large folios at mount time
if the "encrypt" feature is set. However, enabling that feature on a
mounted filesystem circumvents that check, and writing encrypted data
results in a crash:
BUG: kernel NULL pointer dereference, address: 0000000000000028
Workqueue: ext4-rsv-conversion ext4_end_io_rsv_work
RIP: 0010:ext4_finish_bio+0xf7/0x3e0

ext4_release_io_end+0x51/0x110
ext4_end_io_end+0x4c/0xe0
ext4_end_io_rsv_work+0xb3/0x100
Fix this by disabling large folios on encrypted inodes, as is
already done for inodes that use data journaling.
This affects all kernels between v6.19 and v7.2, but it is not needed
in v7.3, where the code was significantly refactored. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Build the cid tables privately and publish them with RCU
The cid tables are visible to the cid kfuncs while being modified: the
first enable publishes the global pointers before filling them,
ops.init_cids() overrides rewrite them in place, and re-enables rebuild
them in place. A racing TRACING or SYSCALL program can read unfilled
entries, including uninitialized memory in the kmalloc'd tables, or torn
topo updates.
Tie the tables' lifetimes to the root sched instead: each root enable
builds a fresh set privately and publishes the per-table __rcu globals once
the layout is final, and root disable unpublishes and RCU-frees the set. A
non-NULL global is now always a fully built table which stays valid for the
reader's RCU read section, and lookups stay two loads. Kfuncs treat NULL as
no-mapping, also after the scheduler exits instead of reporting the stale
last mapping.
The cid kfuncs are available whether the root scheduler is cid-form or
cpu-form, the latter to allow gradual migration to cids. Every root
therefore builds and publishes a default mapping.
Every reader must either be gated on scheduler liveness or NULL-check
inside an RCU read section. Fix the two kfuncs that were neither:
scx_bpf_this_cid() read the table with no RCU or preemption protection and
scx_bpf_task_cid() relied on KF_RCU, which doesn't put a sleepable program
in an RCU read section. The hotplug callbacks are instead serialized by
retiring the tables inside the cpus_read_lock() section that clears
scx_root.
v2: Document why every root builds the tables (desc + cid.c comment). |
| In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_flower: Fix port range register leak in tmplt_create()
mlxsw_sp_flower_tmplt_create() parses a flow_cls_offload template
into a stack-local struct mlxsw_sp_acl_rule_info purely to compute
rulei.values.elusage. Parsing can acquire port range registers via
mlxsw_sp_flower_parse_ports_range(), but since this rulei never goes
through mlxsw_sp_acl_rulei_destroy(), those registers were never
released, including through chain template deletion.
Factor out of mlxsw_sp_acl_rulei_destroy() the code to actually
release the necessary resources and call from
mlxsw_sp_flower_tmplt_create() to plug the leak.
The issue was found during a review of Wentao Liang's patch referenced
below. |
