CVE-2023-7024
Memory Safety in Debian Linux 11.0 … 12.0
Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/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-2023-7024 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Debian Debian Linux. 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 6% 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.
A heap buffer overflow vulnerability, tracked as CWE-787, affects the WebRTC component in Google Chrome versions prior to 120.0.6099.129. The flaw permits heap corruption when a victim visits a crafted HTML page, carrying a CVSS 3.1 base score of 8.8 reflecting network attack vector, low complexity, and no required privileges.
A remote attacker can trigger the issue by serving malicious WebRTC content that the browser processes, achieving potential full compromise of the renderer process with impacts to confidentiality, integrity, and availability. User interaction is required in the form of visiting the attacker-controlled page.
Chrome stable channel updates and downstream advisories from Fedora and Gentoo direct users to upgrade immediately to version 120.0.6099.129 or later; the referenced Chromium bug report and release notes confirm the fix was shipped in the December 2023 stable update.
The EPSS score rose sharply from a low baseline to a peak of 0.4807 on 2024-12-27 before receding to the current 0.0307, indicating that exploitation interest emerged well after public disclosure.
