CVE-2026-81893
Gdk-pixbuf: gdk-pixbuf: invalid write in jpeg icc profile parser on error recovery
A flaw was found in gdk-pixbuf. When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the application. To exploit this flaw, an application using gdk-pixbuf must process the malicious JPEG image. Affected version >= 2.26.4
Fixes and workarounds
Workaround
Avoid opening or automatically indexing untrusted JPEG images with applications linked against a vulnerable gdk-pixbuf version until an updated package is installed.
