A flaw was found in the implementation of Intel Transactional Synchronization Extensions (TSX) abortion where a local authenticated attacker with the ability to monitor execution time is able to infer TSX memory state by comparing abort execution times.

This could allow information disclosure via this observed sidechannel for any TSX transaction being executed while an attacker is able to observe abort timing.

A local elevation of privilege using physical access security vulnerability was found in HPE Proliant Gen10 Servers using Intel Innovation Engine (IE). This attack requires a physical attack to the server motherboard. To mitigate this issue, ensure your server is always physically secured. HPE will not address this issue in the impacted Gen 10 servers listed. HPE recommends using appropriate physical security methods as a compensating control to disallow an attacker from having physical access to the server main circuit board.
