Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 86.0.4240.99

Description The issue is related to a use after free error in the printing functionality of Google Chrome for Android. This error occurs when memory is accessed after it has been freed, which can lead to heap corruption. A remote attacker could potentially exploit this issue by using a specially crafted HTML page, allowing them to execute arbitrary code.

Recommendations For versions prior to 86.0.4240.99, update to version 86.0.4240.99 or later to resolve the issue. As a temporary workaround, consider disabling the printing functionality until a patch is available. Restrict access to potentially malicious HTML pages to minimize the risk of exploitation.
