CVE-2025-21909 is a medium severity vulnerability in the Linux kernel's nl80211 wireless subsystem. It involves the improper handling of monitor interface flags where the MONITOR_FLAG_COOK_FRAMES flag can be set simultaneously with other flags, leading to a kernel warning and potential instability when the interface is deleted. The issue arises because the cooked mode takes precedence and causes a missing driver bit, triggering WARN_ONCE() in the kernel.
