CVE-2018-17182

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.18.9

Description An issue in the Linux kernel allows an attacker to trigger a use-after-free via certain thread creation, map, unmap, invalidation, and dereference operations, potentially gaining privileges. The vmacache flush all function in mm/vmacache.c mishandles sequence number overflows.

Recommendations For Linux kernel versions prior to 4.18.9, update to version 4.18.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the vmacache flush all function until a patch is available.
