Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.6.6
Description A race condition exists in the get task ioprio function, allowing local users to potentially gain privileges or cause a denial of service through a crafted ioprio get system call. This issue can lead to a use-after-free scenario.
Recommendations For Linux kernel versions prior to 4.6.6, update to version 4.6.6 or later to resolve the issue. As a temporary workaround, consider restricting access to the ioprio get system call to minimize the risk of exploitation.
