CVSS 7 HIGH
A flaw was found in the Linux kernel's accel/ivpu component. A local attacker could exploit a signed integer truncation vulnerability in the Inter-Process Communication (IPC) receive path. This flaw occurs when a firmware-supplied data size is incorrectly converted, leading to an oversized memory copy operation that can overflow a kernel stack buffer. Successful exploitation could result in a denial of service through a kernel crash and potentially lead to privilege escalation.
