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.","state":0,"publishedAt":"2026-10-15T18:57:18.619+00:00","modifiedAt":"2026-10-21T01:14:06.812+00:00","affected":[{"ecosystem":"https://github.com","name":"adplug","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"adplug\",\n                    \"product\": \"adplug\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"2.4\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"collectionURL\": \"https://github.com\",\n                    \"packageURL\": \"pkg:github/adplug/adplug\",\n                    \"repo\": \"https://github.com/adplug/adplug\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"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","score":6.8,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":5.5,"severity":"MEDIUM"}],"references":["https://hackmd.io/@haind-pwn/adplug-ksm-note-loop-databuf-oob-write","https://github.com/adplug/adplug/blob/e491e382479ed2246f124c96c70d94561dce59b9/src/xsm.cpp#L86-L134","https://github.com/adplug/adplug","https://www.vulncheck.com/advisories/adplug-through-2.4-out-of-bounds-read-via-cxsmplayer-play-note-in-xsm-files"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-110876","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-110876","identifiers":["CVE-2026-110876"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
