An attacker was able to perform an out-of-bounds read or write on a JavaScript `Promise` object. This issue was demonstrated during Pwn2Own Berlin 2025, where it was used to trigger out-of-bounds memory access. The vulnerability allows for code execution.

The issue is related to out of bounds memory access in the V8 engine of Google Chrome, allowing a remote attacker to perform arbitrary read/write via a crafted HTML page. This can lead to remote code execution. The vulnerability was demonstrated at Pwn2Own 2024, where it was successfully exploited, and the attackers earned $42,500. The Chromium security severity of this issue is High.

The issue is related to insufficient access controls in the Hyper-V hardware virtualization system of Microsoft Windows, allowing an attacker to potentially elevate their privileges.

The issue is related to insufficient access restrictions in Windows AppX Deployment Extensions, allowing an attacker to elevate their privileges using a specially crafted application. This can affect the system, potentially leading to privilege escalation.

The issue is related to insufficient input validation in the Windows Desktop Bridge application converter, which can be exploited to cause a denial of service. This could allow an attacker to affect the system. No information is available about the estimated number of potentially affected devices or real-world incidents where this issue was exploited.

The issue is related to incorrect code generation management in the Microsoft Jet Red Database Engine and Access Connectivity Engine of Microsoft Windows operating systems. It allows a remote attacker to execute arbitrary code.

A vulnerability in Microsoft Office exists due to insufficient input validation. Exploitation of this issue may allow an attacker to execute arbitrary code.

Name of the Vulnerable Software and Affected Versions: Windows Application Compatibility Client Library (affected versions not specified) Description: The issue is related to the improper handling of registry operations by the Windows Application Compatibility Client Library, which could allow an attacker to gain elevated privileges. To exploit this, an attacker would first need code execution on a victim system and then run a specially crafted application. The security update addresses the vulnerability by ensuring the library properly handles registry operations. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The issue is related to how Internet Explorer handles objects in memory, allowing an attacker to gain the same user rights as the current user. This could lead to memory corruption, enabling an attacker to execute arbitrary code in the context of the current user. If the current user has administrative user rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights.
