CVE-2026-45204 - Vulnerability Details - OpenCVE

Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger OOB access and kernel null pointer dereference in an error path. Null pointer dereference occurs in an error path of a function running in kernel thread of execution leading to kernel exceptions, platform instability and denial of service.
