Description Wade Mealing 2020-10-22 00:40:14 UTC 
A flaw was found in the implementation of Intel  Advanced Vector Extensions (AVX) where a local authenticated attacker with the ability to execute AVX instructions is able to gather AVX register state from previous AVX executions.


This could allow information disclosure of AVX register state.
