DescriptionNVD

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.

AnalysisAI

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. Rated high severity (CVSS 7.1), this vulnerability is low attack complexity. This Out-of-bounds Read vulnerability could allow attackers to read data from memory outside the intended buffer boundaries.

Technical ContextAI
