EUVD-2026-108773

In the Linux kernel, the following vulnerability has been resolved: namespace: refuse an automount below a mount that is in no namespace It's possible to add autmounts even when the parent mount isn't in the mount namespace of the caller. The only requirement we have is that the parent mount...

CVE-2026-98978

The Linux kernel contains a vulnerability where a locked mount could be prematurely expired. A shrinkable mount could become locked if a user namespace owner moved it beneath a locked mount using MOVE_MOUNT_BENEATH , causing the locked property to move to the bottom mount. This allowed the top mo...

EUVD-2026-108772

In the Linux kernel, the following vulnerability has been resolved: namespace: never expire a locked mount Locked mounts are special. They protect the underlying files and directories from being revealed. doumount refuses to unmount locked mounts but shrinksubmounts doesn't. A shrinkable mount ca...

CVE-2026-98977

The Linux kernel contains a vulnerability where attach_recursive_mnt() incorrectly handles mount locking for automounts when propagated across user namespaces . Because the kernel may use the caller's mount namespace to determine the user namespace, automounts accessed during path lookup can resu...

EUVD-2026-108771

In the Linux kernel, the following vulnerability has been resolved: namespace: handle mount locking for automounts correctly If mounts are propagated across user namespaces, attachrecursivemnt locks every copy of the source mount to protect overmounts from vanishing and revealing the underlying...

CVE-2026-98976

The Linux kernel is affected by a vulnerability where the attach_recursive_mnt() function incorrectly transfers the MNT_LOCKED property. Specifically, it transfers the lock from the top mount to the mount moved beneath it during a MOVE_MOUNT_BENEATH operation. This allows a user namespace owner t...

EUVD-2026-108770

In the Linux kernel, the following vulnerability has been resolved: namespace: keep the lock on a mount that a propagated copy is moved beneath attachrecursivemnt transfers MNTLOCKED from the top mount to the mount that is moved beneath it with MOVEMOUNTBENEATH. This allows the owner of a user...

CVE-2026-98975

The Linux kernel contains a vulnerability in the XFS filesystem where xmi_can_exchange_reflink_flags() incorrectly assumed all mappings were moved during an exchange. This caused the reflink flag to be cleared erroneously when an exchange covered both files from offset 0 to i_disk_size. Consequen...

EUVD-2026-108769

In the Linux kernel, the following vulnerability has been resolved: xfs: stop exchanging reflink flags when exchanging mappings When an exchange covers both files from offset 0 to idisksize, xmicanexchangereflinkflags assumes every mapping moved and hands the reflink flag over to the other file...

CVE-2026-98974

The Linux kernel XFS filesystem is vulnerable to an issue where the XFS_IOC_EXCHANGE_RANGE operation incorrectly handles the TO_EOF flag. When a non-zero offset is used, the code incorrectly swaps ondisk and incore file sizes, leading to a file that reports a smaller size while still owning block...

EUVD-2026-108768

In the Linux kernel, the following vulnerability has been resolved: xfs: fix exchange-range-to-eof file size exchange Norbert Szetei posted a patch containing an incomplete description of a bug in XFSIOCEXCHANGERANGE's TOEOF flag. The bug tricks exchange-range into modifying a file so that it has...

CVE-2026-98973

The Linux kernel contains a vulnerability in the drm/bridge component where the drm_bridge_add() function performs an unlocked list_del when re-adding a previously removed bridge. Specifically, the function drops the bridge from bridge_lingering_list without acquiring the bridge_lock . Because br...

EUVD-2026-108767

In the Linux kernel, the following vulnerability has been resolved: drm/bridge: Fix unlocked listdel in drmbridgeadd When re-adding a bridge that was previously removed, drmbridgeadd drops it from bridgelingeringlist without holding bridgelock. Both bridgelist and bridgelingeringlist are protecte...

CVE-2026-98972

The Linux kernel contains a vulnerability in the cgroup/cpuset subsystem where the is_in_v2_mode() helper function could potentially access a stale cpuset_cgrp_subsys.root pointer during a cgroup filesystem rebind. This creates a potential Use-After-Free (UaF) situation. To remediate this, a new ...

EUVD-2026-108766

In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Don't access cpusetcgrpsubsys.root in isinv2mode After seeing the patch 1 to guard isinv2mode with RCU, it makes me realize that isinv2mode may be called in a context where a new cgroup filesystem is being rebound...

CVE-2026-98971

The Linux kernel contains a vulnerability in the gpio: exar driver. The root cause is that gpio_exar_probe() stores an allocated ID in exar_gpio only after registering a cleanup action via devm_add_action_or_reset(). If registration fails, the cleanup action is invoked immediately; however, becau...

EUVD-2026-108765

In the Linux kernel, the following vulnerability has been resolved: gpio: exar: initialize the ID before registering its cleanup devmaddactionorreset invokes the cleanup action immediately when registering the action fails. gpioexarprobe currently stores the allocated ID in exargpio only after...

CVE-2026-98970

The Linux kernel contains a memory leak vulnerability within the drm/vc4 component. Specifically, the vc4_bo_cache_destroy() function purges cached Buffer Objects (BOs) but fails to free the size list , resulting in a memory leak every time an unbind occurs. The provided documents do not include ...

EUVD-2026-108764

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Free the BO cache size list on teardown vc4bocachedestroy purges the cached BOs but never frees the size list, leaking it on every unbind...

CVE-2026-98969

The Linux kernel contains a vulnerability in net/sched where em_text_change() fails to enforce a NUL terminator on the 16-byte algo array. When textsearch_prepare() is called on a TS_AUTOLOAD retry, vsnprintf() may perform an out-of-bounds read if the array is not terminated, leaking adjacent ker...
