Summary
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix call trace observed during I/O with CMF enabled The following was seen with CMF enabled: BUG: using smp_processor_id() in preemptible code: systemd-udevd/31711 kernel: caller is lpfc_update_cmf_cmd+0x214/0x420 [lpfc] kernel: CPU: 12 PID: 31711 Comm: systemd-udevd kernel: Call Trace: kernel: <TASK> kernel: dump_stack_lvl+0x44/0x57 kernel: check_preemption_disabled+0xbf/0xe0 kernel: lpfc_update_cmf_cmd+0x214/0x420 [lpfc] kernel: lpfc_nvme_fcp_io_submit+0x23b4/0x4df0 [lpfc] this_cpu_ptr() calls smp_processor_id() in a preemptible context. Fix by using per_cpu_ptr() with raw_smp_processor_id() instead.
