Severity: high · Patch status: patched · Since 2022-03-28 · CVE-2013-3660
The EPATHOBJ::pprFlattenRec function in win32k.sys in the kernel-mode drivers in Microsoft does not properly initialize a pointer for the next object in a certain list, which allows local users to gain privileges. CISA added CVE-2013-3660 to its Known Exploited Vulnerabilities catalog on Mar 28, 2022, which means attackers are exploiting it in the wild.
What to do
- Apply updates per vendor instructions.
- US federal agencies must remediate by Apr 18, 2022 (BOD 22-01); treat that as the outer limit.
