Google Chromium V8 Inappropriate Implementation Vulnerability
Google · Chromium V8
Google Chromium's V8 JavaScript engine contains an inappropriate implementation flaw, which is present in Google Chrome builds prior to 128.0.6613.84. Exploitation requires a remote attacker to lure a victim to a crafted HTML page, after which the attacker could potentially trigger heap corruption, with no authentication needed but user interaction required.
Inappropriate implementation in V8 in Google Chrome prior to 128.0.6613.84 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
