SUSE CVE-2017-15537

The x86/fpu Floating Point Unit subsystem in the Linux kernel before 4.13.5, when a processor supports the xsave feature but not the xsaves feature, does not correctly handle attempts to set reserved bits in the xstate header via the ptrace or rtsigreturn system call, allowing local users to read...

The vulnerability of the fpregs_state_valid function (arch/x86/include/asm/fpu/internal.h) in the Linux operating system allows a attacker to disclose protected information or cause a service failure.

The vulnerability of the fpregsstatevalid function arch/x86/include/asm/fpu/internal.h in the Linux operating system is due to a “race condition”. Exploiting this vulnerability can allow an attacker to disclose sensitive information or cause service failures...

The vulnerability of the performance optimization function in Lazy FPU context switching of Intel Core processors lies in the lack of protection for service data, allowing attackers to gain unauthorized access to protected information.

The vulnerability of the performance optimization function in Lazy FPU context switching of Intel Core processors is related to the lack of protection for service data. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information...

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...
