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-2026-46166

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...

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...

Linux kernel 安全漏洞

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...
