Windows 11 Version 22H3
Monthly
Local privilege escalation in Windows Kernel across Windows 10, Windows 11 (versions 22H3 through 26H1), and Windows Server 2022 allows authenticated local attackers to gain SYSTEM-level privileges through heap corruption. Microsoft has released patches addressing this CWE-122 heap-based buffer overflow. EPSS data not available for risk quantification, and no CISA KEV listing indicates exploitation has not been publicly confirmed, though the vulnerability's low attack complexity (AC:L) and minimal prerequisites (PR:L) make it attractive for post-compromise privilege escalation in targeted attacks.
