Description
CVE-2026-99060 is a vulnerability in the Linux kernel's mt76 wireless driver for the mt7603 device. It involves the improper initialization of a global station WCID used for frames without a station or vif, including those injected via a monitor interface. This flaw could cause a NULL pointer dereference leading to kernel crashes. The issue has been fixed by initializing the WCID before publishing it. The fix was tested successfully on MT7603 PCIe hardware without causing resets or crashes.
