{"id":"ALPINE-CVE-2026-32249","details":"Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state-\u003eout1-\u003eout without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.","modified":"2026-09-14T16:18:08.148242116Z","published":"2026-03-12T20:16:05.523Z","upstream":["CVE-2026-32249"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-32249"}],"affected":[{"package":{"name":"vim","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/vim?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.1.0011"},{"fixed":"9.2.0140-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-32249.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
