What is CVE-2026-82343?

A flaw has been identified in GIMP's file-psd plugin that arises when processing specific PSD image files. The plugin fails to adequately validate the channel-count parameter, resulting in improper memory bounds checking. This vulnerability can lead to both heap out-of-bounds reads and stack out-of-bounds accesses, which may cause application crashes, denial of service scenarios, or limited disclosures of sensitive memory contents. Users are advised to review their configurations and apply relevant patches to mitigate potential risks.
