An issue was discovered in the Linux kernel through 4.18.8. The vmacacheflushall function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations.
