{"id":"CVE-2026-4647","summary":"Binutils: out-of-bounds read in xcoff relocation processing in gnu binutils bfd library","details":"A flaw was found in the GNU Binutils BFD library, a widely used component for handling binary files such as object files and executables. The issue occurs when processing specially crafted XCOFF object files, where a relocation type value is not properly validated before being used. This can cause the program to read memory outside of intended bounds. As a result, affected tools may crash or expose unintended memory contents, leading to denial-of-service or limited information disclosure risks.","modified":"2026-06-26T03:54:48.253146184Z","published":"2026-03-23T13:37:44.413Z","related":["CGA-v7xc-pc69-85pj"],"database_specific":{"cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/4xxx/CVE-2026-4647.json","cna_assigner":"redhat"},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-4647"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/4xxx/CVE-2026-4647.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4647"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2450302"},{"type":"REPORT","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=33919"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://sourceware.org/git/binutils-gdb.git","events":[{"introduced":"0"},{"last_affected":"a44161c313d46a1b10fd764728a089c26037710a"},{"last_affected":"497f816e7547ec80b87ff4be68e054ac00d03ea0"},{"last_affected":"a17fcd19400181f4b8b45be7715337ed83d7a122"},{"last_affected":"1f1c02597cc199227226251a2ea51fe5f44b4d6d"}],"database_specific":{"source":"CPE_STRING","extracted_events":[{"introduced":"0"},{"last_affected":"4.0"},{"last_affected":"6.0"},{"last_affected":"7.0"},{"last_affected":"8.0"}],"cpe":["cpe:2.3:a:redhat:openshift_container_platform:4.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux:6.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux:7.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*"]}}],"versions":["gdb-8.0-release","gdb-8.0-branchpoint","users/ARM/embedded-binutils-master-2016q4","gdb-7.12-branchpoint","gdb-7.11-branchpoint","gdb-7.10-branchpoint","gdb-7.9-branchpoint","gdb-7.8-branchpoint","gdb-7.7-branchpoint","gdb_7_6-branchpoint","gdb_7_5-branchpoint","gdb_7_4-branchpoint","gdb_7_3-branchpoint","gdb_7_2-branchpoint","gdb_7_1-branchpoint","gdb_7_0-branchpoint","gdb_6_8-branchpoint","gdb_6_7-branchpoint","gdb_6_6-branchpoint","gdb_6_5-branchpoint","gdb_6_4-branchpoint","gdb_6_3-branchpoint","gdb_6_2-branchpoint","gdb_6_1-branchpoint","gdb_6_0-branchpoint","gdb_5_3-branchpoint","gdb_5_2-branchpoint","readline_4_0","gdb-4_18-branchpoint"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-4647.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H"}]}
