Description

In the Linux kernel the following vulnerability has been resolved:

wifi: brcm80211: handle pmk_op allocation failure

The kzalloc() in brcmf_pmksa_v3_op() will return null if the physical memory has run out. As a result if we dereference the null value the null pointer dereference bug will happen.

Return -ENOMEM from brcmf_pmksa_v3_op() if kzalloc() fails for pmk_op.
