CVE-2026-81893

Gdk-pixbuf: gdk-pixbuf: invalid write in jpeg icc profile parser on error recovery

Published Aug 27, 2026 CVSS 3.1 · 4.7 Medium EPSS < 1% KEV · Not listed
Description
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

Remediation

Vendor Workaround

Avoid opening or automatically indexing untrusted JPEG images with applications linked against a vulnerable gdk-pixbuf version until an updated package is installed.
