Known exploited vulnerability

CVE-2010-0232

Microsoft Windows Kernel Exception Handler Vulnerability

What is affected

Vendor Microsoft
Product Windows
Weakness CWE-264

The vulnerability

The kernel in Microsoft Windows, when access to 16-bit applications is enabled on a 32-bit x86 platform, does not properly validate certain BIOS calls, which allows local users to gain privileges.

Required action

Apply updates per vendor instructions.

US federal civilian agencies were required to act by 24 March 2022 under BOD 22-01. The deadline is a compliance date, not a measure of severity — it says nothing about how dangerous the flaw is to anyone else.
