CVE-2026-50682

Microsoft Windows 10 21h2

Out-of-bounds read in Windows Active Directory allows an authorized attacker to deny service over a network.

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
Impact
An attacker can read some data and take the service offline.
Weakness
An out-of-bounds read exposes adjacent memory, often leftover secrets.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
