Affected by this issue is the function _bfd_elf_write_section_eh_frame of the file bfd/elf-eh-frame.c of the component Eh Frame Section Handler. Performing a manipulation of the argument cie_length/fde_length/augmentation_data_size/write_offset results in buffer overflow. Attacking locally is a requirement. The exploit is now public and may be used. The project was informed of the problem early through a bug report but has not responded yet.\n\n## Affected\n\n- `binutils = 2.47`\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 · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-90804.json)\n- **RHSA-2026:47171** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-07-28 · [advisory](https://access.redhat.com/errata/RHSA-2026:47171)","depth":"twilight","depthScore":38,"depthScoreParts":{"impact":26.4,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":203637,"id":"CVE-2026-90804","ts":1789483132001,"field":"exploit_available","old":"false","new":"true"}]}
