Summary
CVE-2022-2294 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Apple Mac Os X. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 0.6% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2022-2294 is a heap buffer overflow vulnerability in the WebRTC component of Google Chrome versions prior to 103.0.5060.114. The flaw, tracked under CWE-787, stems from improper bounds checking that can lead to heap corruption when processing certain inputs.
A remote attacker can exploit the issue by convincing a user to visit a crafted HTML page, achieving arbitrary code execution or other impacts consistent with the CVSS 8.8 rating that reflects network attack vector, low complexity, and no required privileges.
Chrome stable channel updates released on 28 July 2022 address the vulnerability by advancing the browser to version 103.0.5060.114 or later; downstream distributions such as Fedora also issued corresponding package updates to incorporate the fix.
The associated EPSS score rose from a low baseline after disclosure to a peak of 0.1589 on 2024-12-17 before receding to the current value of 0.0150, indicating that exploitation interest materialized well after the original publication.
