Description OSIDB Bzimport 2024-07-12 13:34:21 UTC 
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.
