CVE-2020-14351

Published: 25 September 2020

A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

From the Ubuntu Security Team

It was discovered that a race condition existed in the perf subsystem of the Linux kernel, leading to a use-after-free vulnerability. An attacker with access to the perf subsystem could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Notes

AuthorNote
sbeattie
access to the perf subsystem is restricted via either the CAP_PERFMON or CAP_SYS_ADMIN capabilities, or through loosened settings of the kernel.perf_event_paranoid sysctl. See https://www.kernel.org/doc/html/latest/admin-guide/perf-security.html for more details.
