CVE-2026-68405

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When stopping an Access Point AP VLAN, the system attempts to free network packet buffers SKBs while interrupts are disabled. This improper handling can lead to a situation where network transmission operations occur in an...

CVE-2026-68409

A flaw was found in the mac80211 Wi-Fi driver of the Linux kernel. When an MLO Multi-Link Operation link is removed, the RX statistics per-CPU buffer is freed immediately, while the link container is deferred to RCU Read-Copy-Update. This timing issue can lead to a use-after-free vulnerability,...
