CVE-2026-40918

Application crash via oversized PVR dimensions

Published Apr 15, 2026 · Updated Apr 15, 2026

Denial of service in the GIMP PVR image loader on Red Hat Enterprise Linux 6 through 9 allows local users to crash GIMP with a crafted file. The loader miscalculates storage for attacker-controlled image dimensions, producing a stack-based buffer overflow and out-of-bounds read during PVR decoding. Opening or otherwise processing an untrusted PVR file is required, and the demonstrated consequence is limited to crashing the GIMP process.
