Описание
Improper removal of sensitive information before storage or transfer in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
A flaw was found in the Intel Advanced Vector Extensions (AVX) implementation, where a local authenticated attacker with the ability to execute AVX instructions can gather the AVX register state from previous AVX executions. This vulnerability allows information disclosure of the AVX register state.
