CVE-2026-98890

A flaw was found in the Linux kernel's Libertas wireless driver. When operating in monitor mode, the driver fails to properly validate the length of transmission frames before accessing header data. A local attacker could exploit this flaw by transmitting truncated monitor frames, triggering an out-of-bounds memory read that may lead to a system crash and Denial of Service (DoS) or the disclosure of kernel memory.
