Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.3.3

Description The issue is related to a use-after-free vulnerability in the Linux kernel, specifically in the net/unix/af unix.c file. This vulnerability allows local users to bypass intended AF UNIX socket permissions or cause a denial of service, resulting in a system panic. The exploitation of this issue can be achieved via crafted epoll ctl calls.

Recommendations For Linux kernel versions prior to 4.3.3, update to version 4.3.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the AF UNIX socket to minimize the risk of exploitation.
