Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:55435** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 10) · released 2026-08-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:55435)\n- **RHSA-2026:55865** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 9), Red Hat Enterprise Linux CodeReady Linux Builder (v. 9) · released 2026-08-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:55865)\n- **RHSA-2026:67883** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v. 10.0) · released 2026-09-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:67883)\n- **RHSA-2026:67931** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.2) · released 2026-09-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:67931)\n- **RHSA-2026:67930** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.9.4) · released 2026-09-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:67930)\n- **RHSA-2026:67882** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream EUS (v.9.6) · released 2026-09-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:67882)","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":39.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
