Privilege Escalation

Dirty Cow (CVE-2016-5195)

T1068 · MITRE ATT&CK

Dirty COW (CVE-2016-5195) is a race condition in the Linux kernel's handling of copy-on-write for private read-only memory mappings. A local unprivileged process on an affected kernel may exploit the race to write to data behind a read-only mapping and potentially gain higher privileges, including root. The affected package and resulting impact depend on the distribution's kernel build and fixes; check the vendor advisory rather than relying on an upstream version string alone.
