# CVE-2026-96546: Gimp: gimp: one-byte out-of-bounds heap read in the uncompressed dds loader

Status: published. Published: 2026-09-23. Updated: 2026-11-06.

A one-byte out-of-bounds heap read flaw was found in GIMP's uncompressed DDS image loader. When a user opens an uncompressed DDS image, the file-dds plug-in performs an unconditional one-byte look-ahead after processing the final pixel. This may cause the plug-in to crash if the byte immediately following the pixel buffer is inaccessible; no information disclosure or code execution has been demonstrated.

## Remediation

- workaround: Avoid importing uncompressed DDS images from untrusted sources. No application-level mitigation that preserves processing of untrusted DDS files is known. (source: CNA: redhat)
