Microsoft Windows Kernel Exposed IOCTL with Insufficient Access Control Vulnerability — Microsoft Windows Kernel contains an exposed IOCTL with insufficient access control vulnerability within the IOCTL (input and output control) dispatcher in appid.sys that allows a local attacker to achieve privilege escalation. Listed in the CISA KEV catalog (added 2024-03-04) — confirmed exploited in the wild, not theoretical. It is linked to known ransomware campaigns. FIRST EPSS puts the chance of exploitation in the next 30 days at ~52%. Treat it as real and prioritize remediation over triage.
