CVE-2018-3665

CVE-2018-3665 affects systems using Intel Core-based CPUs with Lazy FP state restore enabled. A local attacker could exploit speculative execution side channels to read FP/SIMD state from other processes or the kernel. Public details in connected docs show Linux kernel mitigations (disable Lazy F...

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...

Speculative register leakage from lazy FPU context switching

ISSUE DESCRIPTION x86 has a hardware mechanism for lazy FPU context switching. On a task switch, %cr0.ts Task Switched gets set, and the next instruction to touch floating point state raises an NM No Math, later known as Device Not Available exception. Traditionally, FPU state has been large in...
