Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.12.9
Description The issue is related to the do get mempolicy() function in the Linux kernel, which is vulnerable to a use-after-free condition. This can be exploited by local users through specially crafted system calls, potentially leading to a denial of service or other unspecified impacts.
Recommendations For Linux kernel versions prior to 4.12.9, update to version 4.12.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the do get mempolicy() function until a patch is available.
