CVE-2026-5201

A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.

An Important heap-based buffer overflow flaw exists in the gdk-pixbuf library's JPEG image loader. This vulnerability can be triggered automatically without user interaction when processing a specially crafted JPEG image, such as during thumbnail generation. Successful exploitation leads to application crashes and denial-of-service conditions in applications utilizing gdk-pixbuf for image handling.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To reduce the risk of exploitation, avoid opening or processing untrusted JPEG image files. This operational control helps prevent the automatic triggering of the vulnerability, for example, during thumbnail generation, which could otherwise lead to application instability.
