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

Description A race condition exists in the rds sendmsg function, allowing local users to cause a denial of service, potentially resulting in a system crash, by utilizing a socket that was not properly bound. This issue is a result of an incomplete fix for a previous problem.

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 rds sendmsg function to minimize the risk of exploitation.
