CVE-2022-1729

Published: 20 May 2022

A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc.

From the Ubuntu Security Team

Norbert Slusarek discovered that a race condition existed in the perf subsystem in the Linux kernel, resulting in a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Notes

AuthorNote
amurray
Ubuntu kernels enable SECURITY_PERF_EVENTS_RESTRICT which sets kernel.perf_event_paranoid >= 3 and so disables unprivileged users from using perf by default. As such in their default configuration, Ubuntu kernels are not able to be exploited by this flaw to achieve local privilege escalation.
Priority

Low

CVSS 3 base score: 7.0
