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.
