A flaw was found in the Linux kernel's MediaTek MT7530 DSA (Distributed Switch Architecture) driver. During device removal or driver unbinding, interrupt mappings are prematurely disposed while the parent interrupt is still active. A local privileged user could trigger this flaw during device unbinding, causing the interrupt thread to dereference a null pointer, resulting in a kernel crash and Denial of Service (DoS).
