CVE-2026-112257: Gimp: gimp: heap out-of-bounds read/write in psd thumbnail loader (load_resource_1033)

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: gimp (AlmaLinux:8) 2:2.8.22-26.module_el8.10.0+4352+8516153e.10; gimp-devel (AlmaLinux:8) 2:2.8.22-26.module_el8.10.0+4352+8516153e.10; gimp-devel-tools (AlmaLinux:8) 2:2.8.22-26.module_el8.10.0+4352+8516153e.10.

Low priority for now. Upgrade to gimp (AlmaLinux:8) 2:2.8.22-26.module_el8.10.0+4352+8516153e.10; gimp-devel (AlmaLinux:8) 2:2.8.22-26.module_el8.10.0+4352+8516153e.10; gimp-devel-tools (AlmaLinux:8) 2:2.8.22-26.module_el8.10.0+4352+8516153e.10 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in GIMP. The PSD thumbnail resource loader performs a BGR-to-RGB channel swap with a fixed 3-byte stride and does not verify that the JPEG thumbnail is RGB. A crafted grayscale PSD thumbnail can cause a heap out-of-bounds read and write in the plug-in process, leading to a crash and potentially arbitrary code execution when the victim browses or opens the file.
