Hi, The following vulnerability was published for gdk-pixbuf. Filling for initial tracking of the upstream issue. CVE-2026-16768[0]: | A flaw was found in gdk-pixbuf. When parsing a specially crafted ICO | file with pixel values that exceed the defined palette range, an | out-of-bounds read can occur due to improper bounds checking against | the actual palette size. This vulnerability causes heap bytes to be | interpreted as valid palette indices and rendered as RGB pixel | values in the output image, allowing an attacker to extract heap | content via the generated output, such as a thumbnail. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
