{"id":"CVE-2026-110876","summary":"AdPlug through 2.4 Out-of-Bounds Read via CxsmPlayer::play_note in XSM Files","details":"AdPlug through 2.4 contains an out-of-bounds read vulnerability in src/xsm.cpp that allows attackers to read before note_table by supplying a negative note index. Attackers can craft an XSM file with the ofTAZ! signature and a song byte of 0x80 or higher, causing a global-buffer-overflow read during playback that may crash affected applications.","modified":"2026-10-17T02:48:20.276276076Z","published":"2026-10-15T18:57:18.619Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-125"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110876.json"},"references":[{"type":"WEB","url":"https://github.com"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110876.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110876"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/adplug-through-2.4-out-of-bounds-read-via-cxsmplayer-play-note-in-xsm-files"},{"type":"PACKAGE","url":"https://github.com/adplug/adplug"},{"type":"ARTICLE","url":"https://github.com/adplug/adplug/blob/e491e382479ed2246f124c96c70d94561dce59b9/src/xsm.cpp#L86-L134"},{"type":"EVIDENCE","url":"https://hackmd.io/@haind-pwn/adplug-ksm-note-loop-databuf-oob-write"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/adplug/adplug","events":[{"introduced":"0"},{"fixed":"e491e382479ed2246f124c96c70d94561dce59b9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.4"},{"fixed":"2.4"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["adplug-2.3.3","adplug-2.3.2","adplug-2.3.1","adplug-2.3","adplug-2.2.1","adplug-2.2","adplug-2.1","adplug-2.0","dos-1.5","adplug-1.5","adplug-1.4","adplug-1.3","winamp-1.2","adplug-1.2","linux-1.0","adplug-1.1","adplug-1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110876.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:N/VA:H/SC:N/SI:N/SA:N"}]}
