CVE-2023-53656

The CVE-2023-53656 issue affects the Linux kernel perf path (drivers/perf: hisi) where a migration of the perf context to the CPU going to teardown can occur because cpu_online_mask() has not yet updated during cpuhp teardown. The result is a call trace (example: __switch_to, __schedule, mutex_lo...
