CVE-2026-98976

The Linux kernel contains a vulnerability where attach_recursive_mnt() incorrectly transfers the MNT_LOCKED property from a top mount to a mount moved beneath it using MOVE_MOUNT_BENEATH. This flaw allows a user namespace owner to replace a locked /proc or its root by exploiting how propagated co...

CVE-2026-98975

The Linux kernel contains a vulnerability in the XFS filesystem where the xmi_can_exchange_reflink_flags() function incorrectly assumes all mappings are moved during an exchange from offset 0 to i_disk_size. This incorrect assumption leads to the clearing of a reflink flag on files that still own...

CVE-2026-98974 xfs: fix exchange-range-to-eof file size exchange

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-2026-98974

The Linux kernel contains a vulnerability in the XFS filesystem involving the XFS_IOC_EXCHANGE_RANGE operation's TO_EOF flag. The root cause is that the code incorrectly swaps ondisk and incore file sizes when a nonzero offset is used, leading to incorrect file size reporting. This discrepancy ca...

CVE-2026-98973 drm/bridge: Fix unlocked list_del in drm_bridge_add()

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-2026-98973

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...

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 ...
