Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.5.2
Description
The issue is related to a use-after-free vulnerability in the
sys recvmmsg function, located in the net/socket.c file of the Linux kernel. This vulnerability can be exploited by remote attackers to execute arbitrary code through vectors involving a recvmmsg system call that is mishandled during error processing.Recommendations
For Linux kernel versions prior to 4.5.2, update to version 4.5.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the recvmmsg system call to minimize the risk of exploitation.
