CVE-2026-82343: Gimp

Medium severity, CVSS 6.1. EPSS: 0.3% chance of exploitation in the next 30 days.

A flaw was found in the file-psd plugin in GIMP. When processing a specially crafted PSD image file, the plugin does not properly validate the channel-count parameter. This incorrect validation leads to improper memory bounds checking, resulting in both a heap out-of-bounds read and a stack out-of-bounds access. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of memory contents.

Affected products

• Gimp Gimp: up to and including 3.3.1
• Red Hat Enterprise Linux: version 6.0 only; version 7.0 only; version 8.0 only; version 9.0 only
