CVE-2026-55892 (GCVE-0-2026-55892)

Vulnerability from cvelistv5 – Published: 2026-06-25 15:32 – Updated: 2026-06-26 18:43

Title

Vim: Out-of-bounds Write in Spell File Prefix Dump

Summary

Vim is an open source, command line text editor. Prior to 9.2.0662, the dump_prefixes() function in src/spell.c walks a spell-file prefix trie iteratively with a depth counter while dumping the prefixes that apply to a word. The counter is bounded only by the trie structure itself; it is never checked against the size of the fixed MAXWLEN-element stack arrays it indexes (prefix[], arridx[], curi[]). A crafted .spl file, loaded when the user dumps the word list, can drive the descent arbitrarily deep, so the function writes past the end of those arrays. This is a stack out-of-bounds write that corrupts the call frame and crashes the editor. This vulnerability is fixed in 9.2.0662.

Severity

5.5 (Medium)

CVE-2026-55895 (GCVE-0-2026-55895)

Vulnerability from cvelistv5 – Published: 2026-06-25 15:31 – Updated: 2026-06-26 03:55

Title

Vim: Vimscript Code Injection in netrw NetrwLocalRmFile() via crafted filename

Summary

Vim is an open source, command line text editor. Prior to 9.2.0663, a Vimscript code injection vulnerability exists in s:NetrwLocalRmFile() in the netrw plugin (runtime/pack/dist/opt/netrw/autoload/netrw.vim) when deleting a local file from the browser. A filename derived from the buffer's directory listing is interpolated into an Ex command line passed to :execute with only the backslash character escaped, allowing a crafted filename containing a bar (|) to terminate the intended command and execute arbitrary Vimscript, including shell commands via :call system() and :!. This vulnerability is fixed in 9.2.0663.

Severity
