CVE-2026-112257
Gimp: gimp: heap out-of-bounds read/write in psd thumbnail loader (load_resource_1033)
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.
Fixes and workarounds
Workaround
Avoid opening or browsing untrusted PSD files in GIMP. If GIMP is unused, remove the gimp package.
