Vulnerability from fkie_nvd - Published: 2024-07-12 13:15 - Updated: 2025-11-03 22:17
Severity ?
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: check n_ssids before accessing the ssids In some versions of cfg80211, the ssids poinet might be a valid one even though n_ssids is 0. Accessing the pointer in this case will cuase an out-of-bound access. Fix this by checking n_ssids first.
