When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-10-02 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-102010.json)\n- **RHSA-2026:73642** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-09-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:73642)\n- **RHSA-2026:74569** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-01 · [advisory](https://access.redhat.com/errata/RHSA-2026:74569)","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":38.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
