In the Linux kernel, the following vulnerability has been resolved:

fanotify: fix false positive on permission events

fsnotify_get_mark_safe() may return false for a mark on an unrelated group,

which results in bypassing the permission check.

Fix by skipping over detached marks that are not in the current group. (NVD)
