RaTasha Tillery-Smith 2023-05-02 18:47:01 UTC Doc Text A flaw use-after-free in the Linux kernel Performance Events subsystem was found in the way user triggers simultaneously perf_group_detach function and remove_on_exec function. A local user could use this flaw to crash the system or potentially escalate their privileges on the system. The Linux kernel's Performance Events subsystem has a use-after-free flaw that occurs when a user triggers the perf_group_detach and remove_on_exec functions simultaneously. This flaw allows a local user to crash or potentially escalate their privileges on the system.
