CVE-2026-63876

A flaw was found in the Linux kernel's zs serial driver. During the initialization of the first serial port, a null pointer dereference occurs when a pointer derived from a null parent device pointer is accessed. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS...
