A use-after-free (UAF) vulnerability in the Linux kernel's tracing/user_events subsystem was resolved. The flaw occurs because the child process inherits a pointer to user_event_mm from the parent without proper reference counting. If allocation fails during fork duplication, the child process may free memory that the parent still references, leading to a UAF condition detected by KASAN. The fix clears the copied pointer on failure to prevent the child from freeing memory it does not own. Join the discussion | GCVE Database | 09/11/2026, 21:31:39 UTC Added: 09/12/2026, 00:42:30 UTC |
