Kernel: FPU state information leakage via lazy FPU restore

A Floating Point Unit FPU state information leakage flaw was found in the way the Linux kernel saved and restored the FPU state during task switch. Linux kernels that follow the "Lazy FPU Restore" scheme are vulnerable to the FPU state information leakage issue. An unprivileged local attacker cou...
