CVE-2022-49537

CVE-2022-49537 is related to the Linux kernel SCSI lpfc path with CMF enabled. The issue arises from this_cpu_ptr() using smp_processor_id() in a preemptible context, leading to an invalid call trace (systemd-udevd 31711) and potential preemption-related bugs. The documented fix is to replace thi...
