NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
