Name of the Vulnerable Software and Affected Versions Microsoft Edge (affected versions not specified)

Description The issue is caused by a buffer overflow in the JavaScript engine of Microsoft Edge, leading to memory corruption. This could allow a remote attacker to execute arbitrary code in the context of the current user by rendering content with objects in memory. If the current user has administrative rights, a successful exploitation could grant the attacker control over the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.
