In the Linux kernel, the following vulnerability has been resolved: Wifi: cfg80211: A use-after-free issue was addressed in the cmpbss function. This issue was introduced due to a quirky behavior of the bssfree function introduced in commit 776b3580178f „cfg80211: Properly track hidden SSID...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: ocb: don’t leave if not joined If there is no OCB state, do not ask the driver/mac80211 to leave, as that would only cause confusion. Since the chandef state can be set or cleared, this is a simple check...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Fix use after free for wext The key information in wext.connect is not reset upon reconnection, and this can retain data from a previous connection. Resetting the key data prevents drivers or mac80211 from...
