Published: 17 February 2022
Summary
CVE-2022-0629 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Fedoraproject Fedora. Its CVSS base score is 7.8 (High).
Operationally, ranked in the top 9.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A stack-based buffer overflow vulnerability, also referenced under CWE-121 and CWE-787, affects the Vim editor in the vim/vim repository prior to version 8.2. The flaw carries a CVSS 3.1 score of 7.8 and permits local attackers to corrupt memory through crafted input that exceeds expected buffer bounds on the stack.
An unauthenticated local attacker can trigger the issue by causing a victim to open a malicious file in an affected Vim binary, satisfying the UI:R requirement in the CVSS vector. Successful exploitation yields full control over the process, enabling arbitrary code execution with impacts to confidentiality, integrity, and availability.
Public references point to a corrective commit in the upstream repository and subsequent distribution advisories, including Debian LTS updates, that address the flaw by patching the affected buffer handling code. The associated EPSS score has remained stable at 0.0529 with no material increase observed after disclosure.
