Microsoft Windows
A privilege escalation vulnerability exists when the Windows kernel fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode.
Exploitation status
- CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
- It is known to have been used in ransomware campaigns.
- US federal civilian agencies are required to remediate it by 2022-04-05. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
Required action
Apply updates per vendor instructions.
