NVD Description

Note: Versions mentioned in the description apply only to the upstream libperf-devel package and not the libperf-devel package as distributed by RHEL.

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

inotify: Avoid reporting event with invalid wd

When inotify_freeing_mark() races with inotify_handle_inode_event() it can happen that inotify_handle_inode_event() sees that i_mark->wd got already reset to -1 and reports this value to userspace which can confuse the inotify listener. Avoid the problem by validating that wd is sensible (and pretend the mark got removed before the event got generated otherwise).
