"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Fix crash passing ERR_PTR to kthread_stop()\n\nevent_test_stuff() calls kthread_run() and unconditionally passes the\nreturned task_struct pointer to kthread_stop(). kthread_run() returns an\nerror pointer such as ERR_PTR(-ENOMEM) when kthread creation fails, for\nexample under memory pressure during the boot-time event self-test.\nkthread_stop() then dereferences the invalid pointer, crashing the kernel.\n\nCheck the result of kthread_run() before passing it to kthread_stop(). Use\nWARN_ON() so that a failure to create the self-test thread does not go\nunnoticed, matching the ring-buffer self-test fix in commit\n91542863abad (\"ring-buffer: Fix crash passing ERR_PTR to kthread_stop()\")."
