There is no fixed version for Centos:7 kernel-rt-kvm.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-kvm package and not the kernel-rt-kvm package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

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 happening we never connect to such an AP.

Improve this situation by checking more carefully and ignoring the ECSA if cfg80211 has previously detected the ECSA element being stuck in the probe response.

Additionally, allow connecting to an AP that's switching to a channel it's already using, unless it's using quiet mode. In this case, we may just have to adjust bandwidth later. If it's actually switching channels, it's better not to try to connect in the middle of that.
