CVE-2023-2235

Published: 1 May 2023

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2.

From the Ubuntu Security Team

It was discovered that the perf subsystem in the Linux kernel contained a use-after-free vulnerability. A privileged local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Notes

AuthorNote
Priority reason:
Ubuntu kernels enable SECURITY_PERF_EVENTS_RESTRICT which sets kernel.perf_event_paranoid >= 2 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.
