{"id":"DEBIAN-CVE-2022-48715","details":"In the Linux kernel, the following vulnerability has been resolved:  scsi: bnx2fc: Make bnx2fc_recv_frame() mp safe  Running tests with a debug kernel shows that bnx2fc_recv_frame() is modifying the per_cpu lport stats counters in a non-mpsafe way.  Just boot a debug kernel and run the bnx2fc driver with the hardware enabled.
