{"id":"CVE-2026-31053","details":"A double free vulnerability exists in librz/bin/format/le/le.c in the function le_load_fixup_record(). When processing malformed or circular LE fixup chains, relocation entries may be freed multiple times during error handling. A specially crafted LE binary can trigger heap corruption and cause the application to crash, resulting in a denial-of-service condition. An attacker with a crafted binary could cause a denial of service when the tool is integrated on a service pipeline.","modified":"2026-07-15T01:49:20.228522773Z","published":"2026-04-06T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31053.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31053.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31053"},{"type":"REPORT","url":"https://github.com/rizinorg/rizin/issues/5753"},{"type":"FIX","url":"https://github.com/rizinorg/rizin/pull/5795"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rizinorg/rizin","events":[{"introduced":"c009cb739ca4fd289e634c2bea432d1e7bcd3676"},{"last_affected":"c009cb739ca4fd289e634c2bea432d1e7bcd3676"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:rizin:rizin:0.8.1:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.8.1"},{"last_affected":"0.8.1"}]}}],"versions":["0.8.1","v0.8.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31053.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
