In the Linux kernel, the following vulnerability has been resolved:

scsi: bnx2fc: Make bnx2fcrecvframe() mp safe

Running tests with a debug kernel shows that bnx2fcrecvframe() 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.
