Namespace-state corruption via failed wiphy rename
Published Oct 14, 2026 · Updated Oct 14, 2026
Namespace-state corruption in Linux cfg80211 allows local users to leave wireless devices inconsistent during namespace moves. In net/wireless/core.c, cfg80211_switch_netns() changes the wiphy namespace before device_rename() moves its sysfs representation, but does not undo the change when renaming fails. Reaching the flaw requires a wireless-device namespace move and an allocation failure; the disclosed consequence is inconsistent namespace state and a kernel warning, not demonstrated code execution.
