CVE-2026-98997

The Linux kernel contains a vulnerability within the amdgpu driver's userq component. The function amdgpu_userq_get_doorbell_index() incorrectly pins any Buffer Object (BO) passed as a doorbell_handle into the doorbell domain. For standard BOs, the TTM subsystem moves them using ttm_bo_move_null(...

CVE-2026-98996

The Linux kernel contains a vulnerability in the propagate_mount_busy() helper function, which fails to correctly identify busy mounts during synchronous unmounting. Due to a logic mismatch with the propagate_umount() function, the kernel may skip reference checks on mount copies that have two or...

CVE-2026-98995

The Linux kernel contains a vulnerability in mnt_change_mountpoint() where it fails to reset the ->overmount pointer of an old parent during a mount move, unlike __umount_mnt(). This discrepancy can occur during a reparent() operation where propagate_umount() moves a surviving overmount. If a ...

EUVD-2026-108788

In the Linux kernel, the following vulnerability has been resolved: statmount: read the parent of an unmounted mount under mountlock statmountmntbasic reads the ids of the parent through m-mntparent with namespacesem held for reading. That's fine for a mount that is in a namespace. Everything abo...

CVE-2026-98994

The Linux kernel contains a vulnerability where the statmount_mnt_basic() function can dereference a mount that has already been freed. This occurs because the function reads m->mnt_parent twice while holding the mount_lock , allowing a concurrent mntput() operation to unmount children and fre...

In the Linux kernel, the following vulnerability has been resolved: namespace: don't inherit MNTUMOUNT in clonemnt MNTUMOUNT gets raised on a mount that umounttree or umountone has taken out of its namespace. It's never cleared. detachmounts unhooks a mount that carries it instead of unmounting i...

CVE-2026-98993

The Linux kernel contains a vulnerability where clone_mnt() fails to mask the MNT_UMOUNT flag. This occurs because clone_mnt() only masks MNT_INTERNAL_FLAGS, which does not include MNT_UMOUNT. Consequently, a mount that was lazily unmounted but kept alive by a file descriptor (e.g., via nsfs or p...
