High [CVE-2026-73072] Heap buffer overflow allows arbitrary code execution
CVE-2026-73072Source published Source updated
Vim is an open source, command line text editor. Prior to 9.2.0846, set_sofo() in src/spellfile.c reuses sl_sal_first[] without resetting values left by set_sal_first(), so a crafted spell file containing an SN_SAL section before an SN_SOFO section causes under-counted mapping lists and attacker-influenced writes beyond a heap allocation. This issue is fixed in version 9.2.0846. A heap buffer overflow in Vim allows a local attacker to cause a denial of service or potentially execute arbitrary code. The flaw is triggered by processing a specially crafted spell file, where the set_sofo() function fails to reset internal data between sections, leading to an out-of-bounds write. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-787. Affected…

- Mitigation guidance
- If spell checking is unused, disable it with set nospell in ~/.vimrc and do not set spelllang. If spell is required, load only trusted .spl files from Vim’s spell directories and do not place untrusted spell files on runtimepath. Additionally, consider disabling modelines (set nomodeline in ~/.vimrc) to prevent untrusted text files from automatically overriding these settings when opened.
