| CVE-2024-0519 | Out-of-Bounds Memory Access in Google Chrome/Chromium V8 (Actively Exploited) Google Chrome's V8 JavaScript engine, in versions prior to 120.0.6099.224, contains an out-of-bounds memory access flaw (CWE-787 out-of-bounds write / CWE-125 out-of-bounds read) that is triggered when a user visits a specially crafted HTML page. A remote attacker who lures a victim to such a page can potentially corrupt the heap and execute code in the context of the browser. Successful exploitation could lead to exposure of sensitive information, data tampering, or denial of service (CVSS 3.1: 8.8 High; user interaction is required). Anyone running a vulnerable Chrome/Chromium build is affected, including downstream products that embed V8, such as Fedora's Chromium/Chrome packages and Couchbase Server. The flaw is being actively exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2024-01-17, and news coverage describes it as one of Google's actively exploited Chrome zero-days patched in January 2024. Do: Update Google Chrome to 120.0.6099.224 or later (and restart the browser so the new version is fully loaded); verify fleet versions via Chrome's version reporting if managing enterprise deployments. Fedora users should install the updated chromium/chrome packages via the distribution's update channel, and Couchbase Server operators should apply the vendor's guidance. Because the flaw is on CISA's KEV catalog, federal and other regulated environments are required to apply vendor mitigations promptly; the only effective mitigation is patching, as no public PoC or alternate workaround is documented. | 8.8 | 4% | KEV |

Google on Tuesday released updates to fix four security issues in its Chrome browser, including an actively exploited zero-day flaw.
The issue, tracked as CVE-2024-0519, concerns an out-of-bounds memory access in the V8 JavaScript and WebAssembly engine, which can be weaponized by threat actors to trigger a crash.
"By reading out-of-bounds memory, an attacker might be able to get secret values, such as memory addresses, which can be bypass protection mechanisms such as ASLR in order to improve the reliability and likelihood of exploiting a separate weakness to achieve code execution instead of just denial of service," according to MITRE's Common Weakness Enumeration (CWE).
Additional details about the nature of the attacks and the threat actors that may be exploiting it have been withheld in an attempt to prevent further exploitation. The issue was reported anonymously on January 11, 2024.
"Out-of-bounds memory access in V8 in Google Chrome prior to 120.0.6099.224 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page," reads a description of the flaw on the NIST's National Vulnerability Database (NVD).
The development marks the first actively exploited zero-day to be patched by Google in Chrome in 2024. Last year, the tech giant resolved a total of 8 such actively exploited zero-days in the browser.
Users are recommended to upgrade to Chrome version 120.0.6099.224/225 for Windows, 120.0.6099.234 for macOS, and 120.0.6099.224 for Linux to mitigate potential threats.
Users of Chromium-based browsers such as Microsoft Edge, Brave, Opera, and Vivaldi are also advised to apply the fixes as and when they become available.
