{"id":"CVE-2026-110599","summary":"L-SMASH through 2.14.5 Double Free in HEVC and H.264 Importer Probe","details":"L-SMASH through 2.14.5 contains a double free vulnerability in hevc_setup_first_summary() and h264_setup_first_summary() in importer/nalu_imp.c that frees borrowed codec-specific objects on error paths. Attackers can supply a crafted Annex-B elementary stream lacking a parseable SPS to lsmash_read_file() or the boxdumper, remuxer, or muxer tools, causing use-after-free, heap corruption, and crashes.","modified":"2026-10-15T02:47:36.309610037Z","published":"2026-10-14T14:16:41.692Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-415"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110599.json"},"references":[{"type":"WEB","url":"https://github.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110599.json"},{"type":"PACKAGE","url":"https://github.com/l-smash/l-smash"},{"type":"ARTICLE","url":"https://github.com/l-smash/l-smash/blob/v2.14.5/importer/nalu_imp.c#L1356-L1378"},{"type":"ARTICLE","url":"https://github.com/l-smash/l-smash/blob/v2.14.5/importer/nalu_imp.c#L697-L715"},{"type":"EVIDENCE","url":"https://hackmd.io/@haind-pwn/cve-2016-20099-2026-110599-l-smash-hevc-importer-double-free"},{"type":"ADVISORY","url":"https://hackmd.io/@haind-pwn/l-smash-hevc-importer-double-free"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110599"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/l-smash-through-2.14.5-double-free-in-hevc-and-h-264-importer-probe"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/l-smash/l-smash","events":[{"introduced":"0"},{"last_affected":"5b85a6bf9ca8924144bd3026b17355638a6b7430"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.14.5"}],"source":"AFFECTED_FIELD"}}],"versions":["v2.14.5","v2.9.1","v2.3.0","v1.13.27","v1.13.2","v1.13.0","v1.12.3","v1.11.15","v1.11.8","v1.11.7","v1.9.1","v1.5.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110599.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
