| In the Linux kernel, the following vulnerability has been resolved:
ocfs2/cluster: keep heartbeat local node stable
o2nm_node_local_store() handles local=0 by stopping o2net and setting
cl_local_node to O2NM_INVALID_NODE_NUM, but it leaves cl_has_local set.
That stale state makes o2nm_this_node() return 255, blocks a later local=1
attempt with -EBUSY, and can feed 255 to heartbeat users that call
o2nm_this_node() dynamically.
Clearing cl_has_local is required when the local node is reset. But
heartbeat threads can still be running at that point. They pin the local
node config item at startup, yet o2hb_do_disk_heartbeat() and thread
teardown re-read o2nm_this_node() for the local slot and for
o2nm_undepend_this_node(). Once local=0 has cleared the live local-node
state, those dynamic reads return O2NM_MAX_NODES, which is also the
invalid node number 255.
Store the local node number in the heartbeat region when the region
starts. Use that stable node for heartbeat slot writes/checks,
negotiation messages, and the final configfs undepend. Stop the heartbeat
loop when the current local node no longer matches the stored node, and
clear cl_has_local together with cl_local_node in the local=0 path so
nodemanager state matches node removal.

| In the Linux kernel, the following vulnerability has been resolved:
HID: asus: refactor the two workqueues and init sequence
Multiple issues have been found within the hid-asus driver:
- unchecked size in asus_raw_event()
- unclean teardown of asus_probe on failure
- possible use-after-free in asus_probe
- multiple workqueue used for jobs where one was enough
- sleeping calls in atomic context
- packets of incorrect size being sent to the keyboard controller
Join the two workqueues into one reusing the stopping mechanism
of the brightness workqueue, use the joined workqueue to also
move the asus_wmi_send_event() sleeping call away from atomic
context and add a size check in asus_raw_event(). |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Remove redundant VPD flash read in sysfs read path
qla2x00_sysfs_read_vpd() called ha->isp_ops->read_optrom() a second time
after releasing optrom_mutex. The repeated read is redundant and, unlike
the first, runs without optrom_mutex held, exposing flash access to
concurrent optrom operations. Drop the duplicate call. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: flush active metadata block group at btree_writepages() start
btree_writepages() writes the btree inode's dirty metadata in ascending
logical address order. On a zoned filesystem only one metadata and one
system block group is active for writing at a time, and
check_bg_is_active() (via btrfs_check_meta_write_pointer()) pivots the
active block group as writeback moves from one block group to the next.
If the active block group sits at a higher logical address than another
block group that also holds dirty metadata, the ascending walk reaches
the lower one first and, to write it, has to finish the active block
group and activate the lower one. It cannot finish a block group that
still has unsent IO, and during WB_SYNC_ALL && !for_sync (commit)
writeback it deliberately refuses to wait for that IO under
fs_info->zoned_meta_io_lock, as that can deadlock. The pivot thus cannot
issue the submission itself either, so it gives up:
btrfs_check_meta_write_pointer() returns -EAGAIN, which
btrfs_write_and_wait_transaction() treats as fatal and aborts the
transaction, forcing the filesystem read-only. This happens
intermittently under metadata-heavy relocation (e.g. fstests btrfs/187).
Flush the active metadata and system block groups at the start of
btree_writepages(), under the fs_info->zoned_meta_io_lock it already
holds, so they have no unsent IO left and the later pivot can finish
them and make forward progress. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet: fix max_qid race between configfs and controller allocation
The function nvmet_subsys_attr_qid_max_store() can race against
nvmet_alloc_ctrl() when a subsystem's max_qid limit is modified.
Suppose max_qid is currently 64. If nvmet_alloc_ctrl() executes:
ctrl->sqs = kzalloc_objs(struct nvmet_sq *, subsys->max_qid + 1);
and at this exact point, a userspace process changes max_qid to 128,
nvmet_subsys_attr_qid_max_store() will set the new max_qid value. It
attempts to delete active controllers to force a reconnect, but the
new controller won't be deleted because it hasn't been added to the
subsys->ctrls list yet.
nvmet_alloc_ctrl() then proceeds and adds the new controller to the
subsys->ctrls list. Later, when nvmet_install_queue() is called, it
will see max_qid set to 128, but the memory allocated for sqs is only
sized for 64 entries. This results in a KASAN out-of-bounds warning
and potential memory corruptions.
Fix this by protecting the queue allocations and list insertion in
nvmet_alloc_ctrl() with down_read(&nvmet_config_sem). Because
nvmet_subsys_attr_qid_max_store() acquires down_write(&nvmet_config_sem)
to modify the attribute, this safely prevents the configfs writer from
modifying max_qid during controller creation.
Copy the max_qid from the subsystem to the controller's structure
during the allocation; ctrl->max_qid never changes as long as the
controller remains in LIVE state, so this will prevent similar race
conditions. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: retry verity reads for not-uptodate Merkle folios
btrfs_read_merkle_tree_page() can find a folio in the mapping that is not
uptodate. After taking the folio lock, the current code treats that state
as a read error and returns -EIO.
That can make a previous transient read failure sticky. If the failed read
left a not-uptodate folio in the mapping, later callers find that folio and
fail instead of retrying the read.
Keep the existing page-cache insertion and locking order, but retry the
Merkle item read when a not-uptodate folio is found in the mapping. Also
unlock the folio when read_key_bytes() fails so that a later caller can
lock it and retry the read. |
| On affected platforms running Arista EOS, when multiple gRPC Network Security Interface (gNSI) transports are configured, a race condition in the gNSI Authz service may cause a policy rotation to fail silently. An authenticated user whose access was revoked by the new policy may retain unauthorized access to gRPC interfaces. This does not affect Bootz.
This issue was discovered internally by Arista, and the company is not aware of any malicious exploitation of this vulnerability in customer networks. |
| mport is the MidnightBSD Package Manager. Prior to 2.7.8, directory assets handled as ASSET_DIR or ASSET_DIR_OWNER_MODE in libmport/bundle_read_install_pkg.c used path-based mport_mkdirp(), ownership, and permission operations. A local attacker able to modify part of the target installation tree could use dot-dot traversal or substitute symlinks during privileged package installation, causing directory creation or attribute changes to affect attacker-selected paths outside the intended package directories. This issue is fixed in version 2.7.8. |
| mport is the MidnightBSD Package Manager. Prior to 2.7.8, do_actual_install() in libmport/bundle_read_install_pkg.c used path-based lstat(), chown(), stat(), and chmod() operations while installing package files. A local attacker with write access to a target directory could replace a checked file with a symlink before privileged ownership or mode changes were applied, redirecting those changes to an attacker-selected path and compromising filesystem integrity or permissions. This issue is fixed in version 2.7.8. |
| A race condition was addressed with improved state handling. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27 and iPadOS 27, macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, watchOS 27. An app may be able to cause unexpected system termination. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg
Issuing two writes to the same af_alg socket is bogus as the
data will be interleaved in an unpredictable fashion. Furthermore,
concurrent writes may create inconsistencies in the internal
socket state.
Disallow this by adding a new ctx->write field that indiciates
exclusive ownership for writing. |
| Snipe-IT 8.6.3 and earlier (and develop pre-release commits prior to the fix) contain a race condition in the asset checkout paths. Api\AssetsController::checkout() and Assets\AssetCheckoutController::store() call Asset::availableForCheckout() outside the mutation path and then invoke Asset::checkOut() without taking a row lock or re-checking availability, so two concurrent checkout requests for the same available asset can both observe it as available and both commit. This produces duplicate checkout-history rows, a doubled checkout_counter, and two CheckoutableCheckedOut events for a single-assignment asset, corrupting the audit trail and utilization/reconciliation reporting; the asset's final assigned_to remains singular, so the visible assignment stays intact. Exploitation requires an authenticated session holding the assets.checkout permission (or superuser) and precise concurrent timing. Fixed in 8.7.0. |
| Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. Prior to 0.11.0, Open WebUI resolved a hostname during URL validation and rejected private, loopback, and link-local addresses, but the HTTP clients resolved the hostname again at connection time. An authenticated attacker who controlled authoritative DNS for a submitted hostname could answer with a public address during validation and an internal one during connection, reaching cloud metadata, loopback admin APIs, or internal services through URL ingest, chat image_url fetches, image editing, or OAuth profile-picture fetches, with most paths returning the response to the attacker and the OAuth path forwarding the OAuth access token. This issue is fixed in 0.11.0. |
| Race condition in Core in Google Chrome prior to 153.0.8010.47 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High) |
| Race condition in Extensions in Google Chrome on on Mac prior to 153.0.8010.47 allowed a remote attacker who had compromised the renderer process to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: High) |
| uniget is a universal installer and updater for (container) tools. Prior to 0.27.6, the hooks edit command in cmd/uniget/hooks.go concatenates an unvalidated hook filename with the selected hooks directory, allowing parent-directory components to escape that directory. The resulting path is passed to the configured editor, which can access or modify files outside the hooks directory with the privileges of the uniget process account. This issue is fixed in version 0.27.6. |
| Race condition in PlatformIntegration in Google Chrome on on Mac prior to 153.0.8010.47 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to obtain sensitive information via a crafted HTML page. (Chromium security severity: High) |
| Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to 1.6.6 and from 1.7.0 until 1.7.3, SAML.getSession in internal/pkg/auth/interceptor/saml.go checks SAMLAssertion.Used and marks it used in separate state operations. Concurrent requests carrying the same captured saml-session token can each observe the assertion as unused and obtain authentication as the victim before either update is visible. The attacker can invoke SAML-protected gRPC endpoints, use ConfirmPublicKey to create multiple persistent credentials tied to the victim, and generate audit entries attributed to the victim, with the resulting access potentially affecting confidentiality, integrity, and availability according to the victim's privileges. This issue is fixed in versions 1.6.6 and 1.7.3. |
| In the Linux kernel, the following vulnerability has been resolved:
drm: fix race between partial drm_dev_register() failure and ioctl
If drm_dev_register() fails after registering a minor (e.g. render minor
registered, primary minor fails), userspace could have opened the first
minor and entered a drm_dev_enter() critical section. Since the
unplugged flag was never set, the ioctl proceeds while the error path
tears down device resources.
Fix this by introducing drm_dev_synchronize_unplug(), which sets the
unplugged flag and waits for the SRCU barrier, ensuring all in-flight
drm_dev_enter() critical sections complete before cleanup proceeds; call
it on the error path of drm_dev_register(). |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: fix folio_nr_pages() race after put in large folio invalidate
Our v6.18 based Android system is continuely suffering livelock and bad
page stat as shown in[1] which related to broken xarray slot status. By
investigating big folio operations within f2fs, we find below races and
fix it by get the nr_pages before drop the refcount and folio_lock.
f2fs_get_read_data_folio() calls f2fs_folio_put() before
folio_nr_pages() when invalidating a large folio from the page cache.
That unlocks the folio and drops the caller reference, leaving a window
where a concurrent truncate or folio split can shrink the compound folio
or free it before the invalidate range is computed. An undersized range
then leaves split sub-folios in mapping->i_pages, which can later
interact badly with truncate and reclaim (stale xarray entries and bad
page state when folio->mapping no longer matches the mapping being
truncated).
