SUSE CVE-2024-26683

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: detect stuck ECSA element in probe resp We recently added some validation that we don't try to connect to an AP that is currently in a channel switch process, since that might want the channel to be quiet or we...

SUSE CVE-2024-26682

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: improve CSA/ECSA connection refusal As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is...

CVE-2024-26683

A vulnerability was found in the Linux kernel. This issue occurs when an AP continually advertises a stuck ECSA element, leading to incorrect channel switch process handling. This can lead to network connectivity issues if the AP is stuck in a state where it continuously advertises a false channe...
