DescriptionCVE.org

Type Confusion in V8 in Google Chrome prior to 147.0.7727.101 allowed a remote attacker to potentially perform out of bounds memory access via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Remote code execution in Google Chrome's V8 JavaScript engine (versions before 147.0.7727.101) allows an attacker who convinces a user to visit a crafted HTML page to perform out-of-bounds memory access, potentially leading to full system compromise. There is no evidence of active exploitation, and the exploitation probability is very low (EPSS 0.07%). The flaw is classified as Medium severity by Chromium due to the required user interaction.
