Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 86.0.4240.183

Description The issue is related to an inappropriate implementation in the V8 engine of Google Chrome, which can lead to heap corruption. A remote attacker can potentially exploit this issue via a crafted HTML page, affecting the confidentiality, integrity, and availability of protected information.

Recommendations For versions prior to 86.0.4240.183, update to version 86.0.4240.183 or later to resolve the issue. As a temporary workaround, consider avoiding the use of crafted HTML pages that could trigger the heap corruption until a patch is applied. Restrict access to sensitive information and ensure that only trusted sources are used to minimize the risk of exploitation.
