CVE-2026-53257
A flaw was found in the Linux kernel. An issue within the mac80211 Wi-Fi subsystem, specifically related to the enforcement of High Efficiency HE and Extremely High Throughput EHT capabilities and operations, could lead to a system crash. This vulnerability arises when HE/EHT capabilities are set...
EUVD-2026-39208
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: enforce HE/EHT cap/oper consistency Xiang Mei reports that mac80211 could crash if ehtcap is set but ehtoper isn't. Rather than fixing that for the individual users, enforce that both HE/EHT have consistent elemen...

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...
kernel: wifi: mac80211: use safe list iteration in radar detect work
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...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result
A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

In the Linux kernel, the following vulnerability has been resolved: Wifi: mac80211: mesh: Fixed a leak of meshpreqqueue objects The hwmp code uses objects of type meshpreqqueue, which are added to a list in ieee80211ifmesh to track mpath. We need to fix this issue. If the mpath is deleted, the ex...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: Wifi: mac80211: mlme: Fixed the issue where a null pointer dereference occurred when association with an AP without a link 0 failed. If the association with an AP without a link 0 fails, we may crash during tracing. This occurs...
