CVE-2026-82324

Crash or heap disclosure via HAM row mismatch

Published Aug 28, 2026 · Updated Aug 28, 2026

Out-of-bounds read in GIMP's file-iff plugin on Red Hat Enterprise Linux 9 allows local users to crash GIMP with a crafted IFF/ILBM file. The loader accepts nPlanes=0 and fails to validate the HAM row size, producing a row-size mismatch that bypasses heap bounds checks. A user must open the file in GIMP; successful triggering causes an application crash or limited disclosure of adjacent heap contents.
