Description
A flaw was found in the Linux kernel's TH1520 HDMI bridge driver. During device removal, the driver's teardown callback retrieves driver private data using an incorrect data structure type and passes an invalid pointer to the cleanup routine. A local privileged user could trigger this issue when unbinding the device or unloading the driver, leading to memory corruption and a system crash resulting in a Denial of Service (DoS).
