The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ring-buffer: Fix crash passing ERR_PTR to kthread_stop() In test_ringbuffer()'s out_free cleanup loop, the     check `!rb_threads[cpu]` only catches NULL entries and misses entries that hold an ERR_PTR. rb_threads[]     is static, so unassigned slots are NULL. But when kthread_run_on_cpu() fails for a cpu, it stores     ERR_PTR(-ENOMEM) (or -EINTR) in rb_threads[cpu] before the creation loop jumps to out_free. That entry is     non-NULL, so the old `!ptr` check does not break, and the cleanup proceeds to call kthread_stop() on the     ERR_PTR. kthread_stop() then dereferences the bogus pointer, crashing the kernel during the late_initcall     self-test. crash logs: BUG: kernel NULL pointer dereference, address: 000000000000001c Oops: 0002 [#1] SMP     NOPTI CPU: 1 PID: 1 Comm: swapper/0 Not tainted 7.2.0-rc6-dirty #7 PREEMPT(lazy) RIP:
