kernel, the following vulnerability has been resolved:\n\nproc: protect ptrace_may_access() with exec_update_lock (FD links)\n\nproc_pid_get_link() and proc_pid_readlink() currently look up the task from\nthe pid once, then do the ptrace access check on that task, then look up\nthe task from the pid a second time to do the actual access.\nThat's racy in several ways.\n\nTo fix it, pass the task to the ->proc_get_link() handler, and instead of\nproc_fd_access_allowed(), introduce a new helper call_proc_get_link() that\nlooks up and locks the task, does the access check, and calls\n->proc_get_link().","epss":{"date":"2026-11-09","percentile":0.01056,"score":0.00105},"exploits":[],"kev":null,"metrics":[{"score":7.8,"severity":"high","source":"CNA:
