| In the Linux kernel, the following vulnerability has been resolved:
drm: Account property blob allocations to memcg
DRM_IOCTL_MODE_CREATEPROPBLOB allows userspace to allocate arbitrary-sized
property blobs backed by kernel memory.
Currently, the blob data allocation is not accounted to the allocating
process's memory cgroup, allowing unprivileged users to trigger unbounded
kernel memory consumption and potentially cause system-wide OOM.
Mark the property blob data allocation with GFP_KERNEL_ACCOUNT so that the memory
is properly charged to the caller's memcg. This ensures existing cgroup
memory limits apply and prevents uncontrolled kernel memory growth without
introducing additional policy or per-file limits. |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: fiemap page fault fix
In gfs2_fiemap(), we are calling iomap_fiemap() while holding the inode
glock. This can lead to recursive glock taking if the fiemap buffer is
memory mapped to the same inode and accessing it triggers a page fault.
Fix by disabling page faults for iomap_fiemap() and faulting in the
buffer by hand if necessary.
Fixes xfstest generic/742. |
| In the Linux kernel, the following vulnerability has been resolved:
media: pvrusb2: fix URB leak in pvr2_send_request_ex
When pvr2_send_request_ex() submits a write URB successfully but fails to
submit the read URB (e.g. returns -ENOMEM), it returns immediately without
waiting for the write URB to complete. Since the driver reuses the same
URB structure, a subsequent call to pvr2_send_request_ex() attempts to
submit the still-active write URB, triggering a 'URB submitted while
active' warning in usb_submit_urb().
Fix this by ensuring the write URB is unlinked and waited upon if the read
URB submission fails. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: CGX: fix bitmap leaks
The RX/TX flow-control bitmaps (rx_fc_pfvf_bmap and tx_fc_pfvf_bmap)
are allocated by cgx_lmac_init() but never freed in cgx_lmac_exit().
Unbinding and rebinding the driver therefore triggers kmemleak:
unreferenced object (size 16):
backtrace:
rvu_alloc_bitmap
cgx_probe
Free both bitmaps during teardown. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm_user: fix info leak in build_mapping()
struct xfrm_usersa_id has a one-byte padding hole after the proto
field, which ends up never getting set to zero before copying out to
userspace. Fix that up by zeroing out the whole structure before
setting individual variables. |
| In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid allocate block from corrupted group in ext4_mb_find_by_goal()
There's issue as follows:
...
EXT4-fs (mmcblk0p1): Delayed block allocation failed for inode 206 at logical offset 0 with max blocks 1 with error 117
EXT4-fs (mmcblk0p1): This should not happen!! Data will be lost

EXT4-fs (mmcblk0p1): error count since last fsck: 1

EXT4-fs (mmcblk0p1): last error at time 1765597433: ext4_mb_generate_buddy:760
...
According to the log analysis, blocks are always requested from the
corrupted block group. This may happen as follows:
ext4_mb_find_by_goal
ext4_mb_load_buddy
ext4_mb_load_buddy_gfp
ext4_mb_init_cache
ext4_read_block_bitmap_nowait
ext4_wait_block_bitmap
ext4_validate_block_bitmap
if (!grp || EXT4_MB_GRP_BBITMAP_CORRUPT(grp))
return -EFSCORRUPTED; // There's no logs.
if (err)
return err; // Will return error
ext4_lock_group(ac->ac_sb, group);
if (unlikely(EXT4_MB_GRP_BBITMAP_CORRUPT(e4b->bd_info))) // Unreachable
goto out;
After commit 9008a58e5dce ("ext4: make the bitmap read routines return
real error codes") merged, Commit 163a203ddb36 ("ext4: mark block group
as corrupt on block bitmap error") is no real solution for allocating
blocks from corrupted block groups. This is because if
'EXT4_MB_GRP_BBITMAP_CORRUPT(e4b->bd_info)' is true, then
'ext4_mb_load_buddy()' may return an error. This means that the block
allocation will fail.
Therefore, check block group if corrupted when ext4_mb_load_buddy()
returns error. |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: replace qrtr_tx_flow radix_tree with xarray to fix memory leak
__radix_tree_create() allocates and links intermediate nodes into the
tree one by one. If a subsequent allocation fails, the already-linked
nodes remain in the tree with no corresponding leaf entry. These orphaned
internal nodes are never reclaimed because radix_tree_for_each_slot()
only visits slots containing leaf values.
The radix_tree API is deprecated in favor of xarray. As suggested by
Matthew Wilcox, migrate qrtr_tx_flow from radix_tree to xarray instead
of fixing the radix_tree itself [1]. xarray properly handles cleanup of
internal nodes — xa_destroy() frees all internal xarray nodes when the
qrtr_node is released, preventing the leak.

| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sync: fix leaks when hci_cmd_sync_queue_once fails
When hci_cmd_sync_queue_once() returns with error, the destroy callback
will not be called.
Fix leaking references / memory on these failures. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rt2x00usb: fix devres lifetime
USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).
Fix the USB anchor lifetime so that it is released on driver unbind. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm_user: fix info leak in build_report()
struct xfrm_user_report is a __u8 proto field followed by a struct
xfrm_selector which means there is three "empty" bytes of padding, but
the padding is never zeroed before copying to userspace. Fix that up by
zeroing the structure before setting individual member variables. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix leak of rxgk context in rxgk_verify_response()
Fix rxgk_verify_response() to clean up the rxgk context it creates. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix device leak on probe failure
Driver core holds a reference to the USB interface and its parent USB
device while the interface is bound to a driver and there is no need to
take additional references unless the structures are needed after
disconnect.
This driver takes a reference to the USB device during probe but does
not to release it on all probe errors (e.g. when descriptor parsing
fails).
Drop the redundant device reference to fix the leak, reduce cargo
culting, make it easier to spot drivers where an extra reference is
needed, and reduce the risk of further memory leaks. |
| The Symfony Yaml components Inline and Parser, parse some YAML documents inefficiently, so that a small crafted document can take disproportionately long to process, keeping a PHP process busy for seconds or minutes, potentially causing a denial of service in Symfony versions prior to 5.4.56, 6.x prior to 6.4.50, 7.x prior to 7.4.23, and 8.x prior to 8.1.11.
The parser repeats work it has already done in several places. An embedded mapping in a flow sequence is parsed again for every scalar appended to it, and so are the collections nested in it, so the parse time grows exponentially with the nesting depth. The patterns matching mapping keys and tags scan a run of spaces once per character of the run, and each scalar of a flow collection is matched against a copy of the rest of the collection, so the parse time grows quadratically with the size of the input. Nested blocks are also copied at each nesting level, which consumes memory as well as time. A few other constructs, such as an empty sequence item followed by a blank line or an anchor named 0, trigger similar repeated work.
Any code parsing untrusted YAML is affected, with the default flags. In Symfony 7.4 and later, that includes #[MapRequestPayload] when the Yaml component is installed and the endpoint does not restrict acceptFormat. A single unauthenticated request with a YAML content type keeps a PHP worker busy until max_execution_time. JSON documents are valid YAML, so a JSON payload sent with a YAML content type is enough for the flow collection case. In Symfony 6.4, #[MapRequestPayload] accepts YAML only when the application registers a yaml request format. |
| Wazuh Manager from 3.0.0 before 4.14.9 contains a memory leak vulnerability in the generic JSON decoder that allows remote attackers to exhaust wazuh-analysisd memory via repeated static fields. Attackers can enroll an agent through passwordless enrollment and send events with duplicate fields such as id, triggering an OOM kill that disables alerting. |
| ESP-Protocols is a collection of protocol components for ESP-IDF. Prior to mDNS version 1.11.2, the `mdns` component follows DNS name-compression pointers recursively when parsing fully qualified domain names (FQDNs) in inbound mDNS packets without capping pointer-follow depth in `mdns_utils_read_fqdn()`. An unauthenticated attacker on the same link-local network can send a crafted packet to UDP port 5353 on an `ESP-IDF` device using `espressif/mdns` with mDNS enabled. Deep recursion exhausts the fixed-size stack of the mDNS FreeRTOS task, causing a controlled panic and reboot; persistent malicious traffic can cause a crash loop. No confidentiality or integrity impact has been demonstrated, and remote code execution is not claimed. This issue is fixed in mDNS version 1.11.2. |
| A vulnerability has been identified in armeria-saml versions prior to 1.43.0, where the HTTP-Redirect binding decoder decompresses attacker-supplied SAML messages without limiting the output size before signature validation, allowing an unauthenticated remote attacker to exhaust server memory and cause a denial of service. |
| A vulnerability has been found in laspy up to 2.7.0. Affected by this issue is some unknown functionality of the file laspy/lasreader.py of the component LAS File Handler. The manipulation leads to uncontrolled memory allocation. Remote exploitation of the attack is possible. |
| A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured. The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack. The attacker needs to be able to reach the server with a normal HTTP request. |
| A flaw was found in PostgreSQL involving the pg_cancel_backend role that signals background workers, including the logical replication launcher, autovacuum workers, and the autovacuum launcher. Successful exploitation requires a non-core extension with a less-resilient background worker and would affect that specific background worker only. This issue may allow a remote high privileged user to launch a denial of service (DoS) attack. |
| When an operator enables store.analysis_statistics_dir, a network client with PRODUCT_STORE permission for a product can call that product's storeAnalysisStatistics Thrift-over-HTTP method. CodeChecker 6.29.0 decodes the attacker-controlled Base64 string and passes the complete compressed input to one-shot zlib.decompress(). No maximum decompressed size is enforced.
This gives a correctly authorized, non-superuser store account a high-ratio memory and persistent-disk amplification primitive. The complete output is first materialized as a Python bytes object and is then written to the configured statistics directory. A sufficiently scaled payload can exhaust the API worker or host memory and impair CodeChecker availability.
The shipped value of store.analysis_statistics_dir is null, so the affected feature is disabled by default. The primary assessment does not rely on authentication being disabled. There is no authorization bypass and no path traversal in this report. |
