CVE-2024-27048

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.
