CVE-2026-5201: Heap-based Buffer Overflow in Red Hat Red Hat Enterprise Linux 10
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.
AI Analysis
Technical Summary
The gdk-pixbuf library in Red Hat Enterprise Linux 10 contains a heap-based buffer overflow vulnerability (CVE-2026-5201) in its JPEG image loader. This occurs because the library does not properly validate the number of color components when processing specially crafted JPEG images. An attacker can remotely trigger this vulnerability without requiring user interaction, potentially causing application crashes and denial of service. Red Hat has issued security advisories and released updated gdk-pixbuf2 packages that fix this vulnerability across multiple architectures including x86_64, s390x, ppc64le, and aarch64. The updates are available via official Red Hat errata RHSA-2026:10707 and RHSA-2026:10708. The CVSS v3.1 base score is 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), reflecting a high impact on availability but no confidentiality or integrity impact.
Potential Impact
Exploitation of this vulnerability leads to denial of service conditions through application crashes caused by a heap-based buffer overflow. There is no indication of confidentiality or integrity impact. The vulnerability can be triggered remotely without user interaction, increasing the risk of widespread disruption in affected environments. No known exploits are reported in the wild as of the advisory date.
Mitigation Recommendations
Red Hat has released official security updates for gdk-pixbuf2 that address this vulnerability. Users of Red Hat Enterprise Linux 10 and 9 should apply the updated packages as detailed in Red Hat advisories RHSA-2026:10707 and RHSA-2026:10708. The advisories provide package names and instructions for applying the fix. Applying these updates will remediate the vulnerability and prevent exploitation. Patch status is confirmed as available and official fixes are provided by Red Hat.
