{"id":"CVE-2026-6844","summary":"Binutils: binutils: denial of service vulnerabilities in readelf via crafted elf files","details":"A flaw was found in the `readelf` utility of the binutils package. A local attacker could exploit two Denial of Service (DoS) vulnerabilities by providing a specially crafted Executable and Linkable Format (ELF) file. One vulnerability, a resource exhaustion (CWE-400), can lead to an out-of-memory condition. The other, a null pointer dereference (CWE-476), can cause a segmentation fault. Both issues can result in the `readelf` utility becoming unresponsive or crashing, leading to a denial of service.","modified":"2026-07-08T08:11:37.261266497Z","published":"2026-04-22T08:37:09.794Z","database_specific":{"cna_assigner":"redhat","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/6xxx/CVE-2026-6844.json","cwe_ids":["CWE-400"]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-6844"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/6xxx/CVE-2026-6844.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6844"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2460016"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://sourceware.org/git/binutils-gdb.git","events":[{"introduced":"a44161c313d46a1b10fd764728a089c26037710a"},{"last_affected":"1f1c02597cc199227226251a2ea51fe5f44b4d6d"}],"database_specific":{"cpe":["cpe:2.3:a:redhat:openshift_container_platform:4.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux:7.0:*:*:*:*:*:*:*","cpe:2.3:o:redhat:enterprise_linux:8.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"4.0"},{"last_affected":"4.0"},{"introduced":"7.0"},{"last_affected":"7.0"},{"introduced":"8.0"},{"last_affected":"8.0"}],"source":"CPE_STRING"}}],"versions":["4.0","7.0","8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-6844.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:N/I:N/A:H"}]}
