Description
A flaw was found in the Linux kernel's usb: net: sierra driver. The driver incorrectly handles USB device endpoints by failing to verify that a required interrupt input endpoint is present. A local attacker with low privileges could exploit this omission, potentially leading to a denial of service (DoS), information disclosure, or arbitrary code execution.
