Vulnerability from fkie_nvd - Published: 2024-05-01 13:15 - Updated: 2024-12-23 19:05
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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.
