It was discovered that systems with microprocessors utilizing
speculative execution and indirect branch prediction may allow
unauthorized disclosure of information to an attacker with local
user access via a side-channel analysis (Spectre v2).
Multiple fixes were done already in Linux kernel, intel-microcode,
