GHSA-QF7P-VPJ6-JV2C

Vulnerability from github – Published: 2024-07-12 15:31 – Updated: 2025-11-04 00:30

Details

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.

Severity ?

7.1 (High)
