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...

CVE-2026-46166

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: use safe list iteration in radar detect work The call to ieee80211dfscaccancel can cause the iterated chanctx to be freed and removed from the list. Guard against this to avoid a slab-use-after-free error...

CVE-2026-46166

The CVE-2026-46166 affects the Linux kernel’s wireless subsystem (mac80211) in the radar detect work. The root cause is unsafe list iteration during radar processing, where ieee80211_dfs_cac_cancel can free the iterated chanctx and remove it from the list, causing a slab-use-after-free. A guarded...

Linux Kernel Security Vulnerabilities

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of use of a security list iteration in the mac80211 radar detection process. This...

PT-2026-44289

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A slab-use-after-free error exists in the mac80211 wireless subsystem. The issue occurs during radar detect work when the ieee80211 dfs cac cancel function is called, which can cause the...

ath11k_wmi_pdev_dfs_radar_detected_event Heap Buffer Overflow DoS

The vulnerability of the ath11kwmipdevdfsradetectedevent function in the drivers/net/wireless/ath/ath11k/wmi.c module – the driver for Atheros/Qualcomm wireless adapter support in Linux operating systems – stems from the reutilization of previously freed memory. Exploiting this vulnerability can...
