Google Chromium V8 Out-of-Bounds Memory Write Vulnerability
Google · Chromium V8
Google Chromium's V8 JavaScript engine contains an out-of-bounds write flaw, classified as CWE "Out-of-bounds Write", affecting Google Chrome builds prior to 124.0.6367.207. An attacker who can get a victim to load a crafted HTML page can trigger a memory write outside the intended bounds, with the victim needing to interact with the page (user interaction required) and no network access, authentication, or special configuration on the attacker's side beyond serving that page.
Out of bounds write in V8 in Google Chrome prior to 124.0.6367.207 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: High)
