Microsoft Edge (Chromium) < 144.0.3719.82 Multiple Vulnerabilities

medium Nessus Plugin ID 290257

Synopsis

The remote host has an web browser installed that is affected by multiple vulnerabilities.

Description

The version of Microsoft Edge installed on the remote Windows host is prior to 144.0.3719.82. It is, therefore, affected by multiple vulnerabilities as referenced in the January 16, 2026 advisory.

- Use after free in ANGLE. (CVE-2026-0908)

- Microsoft Edge Elevation Service exposes a privileged COM interface that inadequately validates the privileges of the calling process. A standard (nonadministrator) local user can invoke the IElevatorEdge interface method LaunchUpdateCmdElevatedAndWait, causing the service to execute privileged update commands as LocalSystem. This allows a nonadministrator to enable or disable Windows VirtualizationBased Security (VBS) by modifying protected system registry keys under HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard.
Disabling VBS weakens critical platform protections such as Credential Guard, Hypervisorprotected Code Integrity (HVCI), and the Secure Kernel, resulting in a security feature bypass. (CVE-2026-21223)

- Out of bounds memory access in V8. (CVE-2026-0899)

- Inappropriate implementation in V8. (CVE-2026-0900, CVE-2026-0902)

- Inappropriate implementation in Blink. (CVE-2026-0901)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Microsoft Edge version 144.0.3719.82 or later.
