{"id":"CVE-2026-90804","summary":"GNU Binutils Eh Frame Section elf-eh-frame.c _bfd_elf_write_section_eh_frame buffer overflow","details":"A vulnerability was detected in GNU Binutils 2.47. 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.","modified":"2026-09-20T11:47:29.145740602Z","published":"2026-09-14T17:00:17.351Z","database_specific":{"cna_assigner":"VulDB","cwe_ids":["CWE-119","CWE-120"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90804.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.47"},{"last_affected":"2.47"}]}]},"references":[{"type":"WEB","url":"https://www.gnu.org/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90804.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90804"},{"type":"ADVISORY","url":"https://vuldb.com/cve/CVE-2026-90804"},{"type":"ADVISORY","url":"https://vuldb.com/submit/920281"},{"type":"ADVISORY","url":"https://vuldb.com/vuln/403306"},{"type":"REPORT","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=34445"},{"type":"REPORT","url":"https://vuldb.com/vuln/403306/cti"},{"type":"EVIDENCE","url":"https://github.com/r1ck9-2q/cve_summit/blob/main/Heap%20OOB%20write%20%20negative-size%20%60memmove%60%20%20SEGV%20in%20%60_bfd_elf_write_section_eh_frame%60%20(bfdelf-eh-frame.c2064%20%202083%20%202193)%20via%20malformed%20%60.eh_frame%60.md"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://sourceware.org/git/binutils-gdb.git","events":[{"introduced":"6ce87bbc521cf46eaee9a1f7ef61cee2cdfb3e32"},{"last_affected":"6ce87bbc521cf46eaee9a1f7ef61cee2cdfb3e32"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:gnu:binutils:2.47:*:*:*:*:*:*:*","extracted_events":[{"introduced":"2.47"},{"last_affected":"2.47"}]}}],"versions":["2.47","binutils-2_47"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90804.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P"}]}
