Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The vulnerability is related to the bnx2fc recv frame() function in the Linux kernel, which modifies the per cpu lport stats counters in a non-mpsafe way. This can lead to a bug when using smp processor id() in preemptible code. The issue can be reproduced by running tests with a debug kernel and enabling the bnx2fc driver with the hardware. The vulnerability may cause a denial of service.
