Description
A flaw was found in the Linux kernel's MediaTek MT7603 wireless driver. A local user with network privileges can cause a denial of service (DoS) by transmitting raw frames through a monitor interface. Because the driver publishes its global station tracking structure without proper initialization, queuing these injected frames triggers a NULL pointer dereference that crashes the system.
