Vendor: Intel

Description

The vulnerability allows an adjacent attacker to obtain potentially sensitive information.

The vulnerability exists due to an error in systems with microprocessors utilizing speculative execution and address translations. An adjacent attacker with guest OS privilege can trigger terminal page fault, conduct side-channel attack and gain access to potentially sensitive information residing in the L1 data cache.

Mitigation
Install update from vendor's website.
