A flaw was found in the Linux kernel's USB Type-C TI Power Delivery (tipd) driver. The driver fails to initialize memory for descriptor structures when handling partner device connections. An attacker connecting a USB device can cause the system to invoke uninitialized function pointers, leading to a kernel crash and a Denial of Service (DoS). In addition, uninitialized kernel stack data may be exposed through the system filesystem (sysfs), resulting in information disclosure to a local user.
