kernel: wifi: mac80211: remove station if connection prep fails

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...

CVE-2026-46125

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...

CVE-2026-46166

A flaw was found in the Linux kernel's mac80211 wireless subsystem. This vulnerability arises from unsafe list iteration during radar detection work, where a channel context can be freed while still being processed. This can lead to a use-after-free memory error. A successful exploit could result...

CVE-2026-23444

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This vulnerability occurs because a specific error path within the ieee80211txprepareskb function fails to properly release a network buffer, known as a socket buffer skb. This inconsistency can lead to a double-free condition, wher...
