CVE-2026-98992

The Linux kernel contains a vulnerability in may_copy_tree() where it fails to stop walking an unmounted mount tree. Specifically, when dealing with nsfs or pidfs mounts that are lazily unmounted but kept alive by a file descriptor, recursive operations using MS_REC or AT_RECURSIVE continue to co...

EUVD-2026-108786

In the Linux kernel, the following vulnerability has been resolved: namespace: don't copy an unmounted mount tree maycopytree accepts a mount whose root is an nsfs or pidfs file before it checks whether that mount is mounted. This exception exists for nsfs and pidfs mounts. They are part of no...

CVE-2026-98989

The Linux kernel contains a vulnerability where the do_loopback() function fails to properly check for recursive bind mount loops when using the MS_REC flag. Specifically, while it checks the starting dentry, it allows the copying of mount namespace files from other namespaces. This allows an att...

In the Linux kernel, the following vulnerability has been resolved: dcache: don't put a mountpoint on a dentry that's being removed rmdir, unlink and rename call dontmount on the victim and then detachmounts with the victim's inode locked. dolockmount takes the inode lock of the mountpoint and...

CVE-2026-98982

The Linux kernel contains a vulnerability where a pseudo dentry (for pipes, sockets, etc.) can become the root of a mount via a bind mount of /proc/self/fd/. Because these dentries carry DCACHE_NORCU , they are freed immediately by dentry_free(). If a walker accesses the mount via __follow_mount_...
