Microsoft Windows Kernel Exception Handler Vulnerability (CVE-2010-0232)
Severity: high · Patch status: patched · Since 2022-03-03 · CVE-2010-0232
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. CISA added CVE-2010-0232 to its Known Exploited Vulnerabilities catalog on Mar 3, 2022, which means attackers are exploiting it in the wild.
What to do
- Apply updates per vendor instructions.
- US federal agencies must remediate by Mar 24, 2022 (BOD 22-01); treat that as the outer limit.
