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.
