This vulnerability involves an integer overflow or wraparound in the Windows Kernel component of Microsoft Windows 10 Version 1607 (build 10.0.14393.0). Exploitation requires local access with some level of authorization and can result in privilege escalation, granting the attacker higher system privileges. The CVSS 3.1 vector indicates low attack complexity and privileges required, with no user interaction needed. Microsoft has published an official fix addressing this vulnerability.

Successful exploitation allows an authorized local attacker to elevate their privileges, potentially gaining higher-level access to the system. This can lead to full system compromise depending on the privileges escalated to. The vulnerability affects confidentiality, integrity, and availability as indicated by the CVSS impact metrics.

An official fix is available from Microsoft. Users and administrators should apply the security update provided in the Microsoft advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-58532 to remediate this vulnerability.
