- Summary
- [none]
- Details
-
In the Linux kernel through 5.0.2, the function inotifyupdateexistingwatch() in fs/notify/inotify/inotifyuser.c neglects to call fsnotifyputmark() with INMASKCREATE after fsnotifyfindmark(), which will cause a memory leak (aka refcount leak). Finally, this will cause a denial of service.
