Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: mac80211: Fixed a deadlock issue in AP/VLAN handling. Syzbot reports that when APVLAN interfaces are active, closing the AP interface they belong to can lead to a deadlock. This isn’t surprising—since we use devclose to handle...

CVE-2025-38643

CVE-2025-38643 affects the Linux kernel wifi stack (cfg80211). The root cause is a missing lock in cfg80211_check_and_end_cac(), while callers of wdev_chandef() are expected to hold the wiphy mutex; however the worker cfg80211_propagate_cac_done_wk() does not acquire it. This can trigger a warnin...

PT-2025-34404

Name of the Vulnerable Software and Affected Versions: Linux kernel versions 6.14.0-rc5-wt-g03960e6f9d47 33 and earlier. Description: A missing lock in the cfg80211 check and end cac function within the Linux kernel's wireless subsystem can lead to issues when callers of wdev chandef do not hold...

CVE-2021-47225

A vulnerability was found in the Linux kernel's mac80211 module, where closing an active AP interface while its associated APVLAN interfaces are still up can lead to a deadlock. This situation occurs because the system tries to lock a resource that is already held, causing the operation to freeze...

CVE-2021-47225

Linux kernel mac80211 deadlock when AP_VLANs are up and the AP interface is closed. Root cause: dev_close() held the wiphy mutex triggers netdev cfg80211 notifier to re-acquire the wiphy mutex. Fixes described: (1) prevent changing iftype while AP_VLANs are up; (2) move the dev_close() loop over ...
