CVE-2026-49747: Imagination GPU DDK integer overflow in buffer mapping

CVE-2026-49747 · Severity: info · Published 2026-11-13

A non-privileged user can exploit an integer overflow flaw in Imagination's GPU driver when mapping large GPU buffers to cause out-of-bounds memory writes. This can lead to kernel panics or memory corruption that an attacker might leverage for privilege escalation or system compromise.

Technical details

An integer overflow occurs in the GPU DDK kernel module when mapping GPU buffers larger than 4GB, corrupting the array length metadata. A non-privileged user can trigger this via GPU system calls, leading to out-of-bounds writes to GPU buffers and potential kernel panic or memory corruption. The vulnerability requires local access and GPU system call capabilities.
