A flaw was found in the Linux kernel's accel/rocket module. During error handling in the rocket_ioctl_submit_job() function, a cleanup routine may attempt to free a job->domain pointer that has not yet been initialized, leading to a NULL pointer dereference. A local attacker could exploit this vulnerability to trigger a system crash, resulting in a Denial of Service (DoS).
kernel: accel/rocket: initialize job domain before cleanup paths — rated Moderate by Red Hat. Released 2026-09-11, updated 2026-09-21.
