The vulnerability of the cfg80211_pmsr_wdev_down() function in the net/wireless/pmsr.c module, which supports wireless communication in Linux kernels, allows a attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the cfg80211pmsrwdevdown function in the net/wireless/pmsr.c module, which supports wireless communication in Linux kernel, is related to the race condition that occurs when a shared resource is used. Exploiting this vulnerability could allow an attacker to compromise the...

CVE-2026-68406

A flaw was found in the cfg80211 component of the Linux kernel's Wi-Fi subsystem. This vulnerability allows the PMSR FTM request parser to accept preamble values outside the defined nl80211 range. An attacker could exploit this by providing malformed input, potentially leading to unexpected syste...

CVE-2026-68408

The CVE affects the Linux kernel cfg80211/pmsr handling in wifi: the deadlock occurred when a PMSR session was closed during device teardown: wdev_down held wiphy_lock, while pmsr_free_wk waited to acquire the same lock via cancel_work_sync. The fix converts pmsr_free_wk from a plain work_struct ...
