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-2026-68404

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. This vulnerability involves a race condition during the process of disconnecting a wireless device, where a work item can be improperly queued after it has been cancelled. This could allow a local attacker to trigger a system...

CVE-2026-68412

A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the cfg80211 component. This vulnerability, located in the cfg80211wextsiwscan function, can lead to a memory leak. A local attacker could exploit this by sending a crafted Wi-Fi scan request with an Extended Service Set...

CVE-2026-68402

A flaw was found in the Linux kernel's Wi-Fi subsystem cfg80211. The cfg80211iselementinherited function does not properly validate the length of extension elements. A remote attacker, by sending a specially crafted Wi-Fi frame from an Access Point AP, could trigger a one-octet slab-out-of-bounds...

CVE-2026-68414

A flaw was found in the Linux kernel's cfg80211 Wi-Fi subsystem. When a Wi-Fi device is unregistered, the system fails to properly cancel pending scheduled scan results work. This can lead to a use-after-free vulnerability, where the system attempts to access memory that has already been released...

CVE-2026-68408

A flaw was found in the Linux kernel's wifi: cfg80211 component. A local attacker could trigger a system deadlock by performing specific concurrent operations related to wireless interface management. This race condition occurs when a wireless interface is being torn down while a related network...

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Fix an error handling path in cfg80211wextsiwscan If the test against IEEE80211MAXSSIDLEN fails, then 'creq' leaks. Use the existing error handling path to fix it...

EUVD-2026-55594

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: convert pmsrfreewk to wiphywork to fix deadlock When a netlink socket that owns a PMSR session is closed, cfg80211releasepmsr clears the request's nlportid and queues pmsrfreewk to call cfg80211pmsrprocessabort...

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 ...
