Description msiddiqu 2020-03-31 18:46:55 UTC 
A vulnerability was found in mnh driver in Kernel where there is a race condition due to insufficient locking. This could lead to a use-after-free which could lead to escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
