A vulnerability in the Linux kernel's mount notification system allows a mount to be queued multiple times for notifications, leading to use-after-free memory access. This occurs because mnt_notify_add() does not check if a mount is already on the notification list, causing corrupted list state and potential kernel memory errors. The issue affects mounts with the MNT_SHRINKABLE flag, such as submounts of NFS, AFS, CIFS, and tracefs. The flaw has been resolved by initializing the notification list properly and preventing duplicate queueing of mounts.
