CVE-2026-108462: Windows Kernel Information Disclosure Vulnerability
Microsoft has identified a Windows kernel information disclosure flaw (CVE‑2026‑108462) that permits local attackers with elevated privileges to read sensitive system data. The issue is fixed in the latest security update; administrators should apply the patch immediately and verify that kernel memory is protected.
What happened
A flaw in the Windows kernel allows an attacker with local access and sufficient privileges to read kernel memory, exposing sensitive system information. The vulnerability is triggered by an unauthorized control sphere that bypasses normal access checks.
Impact
Local attackers can retrieve confidential data such as passwords, cryptographic keys, or configuration details from kernel memory. This may facilitate further privilege escalation or compromise of other processes.
What to do
- Apply the latest Microsoft security update that addresses CVE‑2026‑108462.
- Ensure that accounts with local administrative rights are tightly controlled and monitored.
- Run integrity monitoring tools to detect unauthorized kernel memory reads.
Mitigation
Until the patch is applied, restrict local administrative access and consider disabling unnecessary services that could be exploited to trigger the vulnerability.
