{"id":"DEBIAN-CVE-2026-73075","details":"Vim is an open source, command line text editor. From 9.2.0469 until 9.2.0843, popup_mark_opacity_zindex() in src/popupwin.c can use a negative w_winrow for a text-property-anchored popup with clipwindow and opacity, indexing before the screen array instead of accounting for w_popup_topoff and causing an out-of-bounds read and conditional write. This issue is fixed in version 9.2.0843.","modified":"2026-09-10T08:47:29.301600695Z","published":"2026-08-11T16:17:38.840Z","upstream":["CVE-2026-73075"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-73075"}],"affected":[{"package":{"name":"vim","ecosystem":"Debian:14","purl":"pkg:deb/debian/vim?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:9.2.0858-1"}]}],"versions":["2:9.1.1230-2","2:9.1.1385-1","2:9.1.1766-1","2:9.1.1829-1","2:9.1.1846-1","2:9.1.1882-1","2:9.1.2103-1","2:9.1.2141-1","2:9.2.0119-1","2:9.2.0136-1","2:9.2.0218-1","2:9.2.0315-1","2:9.2.0338-1","2:9.2.0355-1","2:9.2.0428-1","2:9.2.0461-1","2:9.2.0524-1","2:9.2.0782-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-73075.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
