Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 4.12.4
Description
The issue is related to a race condition in the fsnotify implementation. It allows local users to gain privileges or cause a denial of service, such as memory corruption, by leveraging the simultaneous execution of the
inotify handle event and vfs rename functions through a crafted application.Recommendations
For Linux kernel versions through 4.12.4, consider applying a patch or updating to a version that fixes the fsnotify implementation issue to prevent exploitation. As a temporary workaround, consider restricting access to the
inotify handle event and vfs rename functions to minimize the risk of exploitation.Exploit
