CVE-2022-4135
Memory Safety in Google Chrome ≤ 107.0.5304.121
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2022-4135 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Google Chrome. Its CVSS base score is 9.6 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability is a heap buffer overflow in the GPU component of Google Chrome versions prior to 107.0.5304.121, classified under CWE-787 as an out-of-bounds write. It resides in the browser's graphics processing path and carries a CVSS 3.1 score of 9.6 reflecting network attack vector, low complexity, and high impact across confidentiality, integrity, and availability when chained with a renderer compromise.
An attacker who has already gained control of the renderer process can deliver a crafted HTML page to trigger the flaw and attempt a sandbox escape, potentially gaining broader access to the underlying system.
Chrome release notes and the associated Gentoo advisory direct users to update immediately to version 107.0.5304.121 or later; the fix was shipped in the stable channel on 24 November 2022.
The EPSS score rose materially from a low baseline to a peak of 0.1960 on 2025-01-18 before receding, indicating that exploitation interest emerged well after disclosure and that the CVE merits renewed attention.
