Astra Linux – Vulnerability in Linux, Linux 5.10

Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel versions 5.1 through 5.19.x, prior to 5.19.16, could be exploited by local attackers those capable of injecting WLAN frames to trigger use-after-free conditions, potentially allowing them to execute...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: fixed the issue of locking in the ieee80211startap error path. We need to hold the local-mtx to release the channel context; this is even encoded in the lockdepassertheld function. Fix this issue...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: fixed a use-after-free in CCMP/GCMP RX.
