在Spectre-V1攻击方式中,攻击者正式通过这种错误的训练来误导分支预测器,使之做出错误的预测,从而错误地执行某些本不该执行的分支代码;由于Spectre-V1只利用了条件分支预测器,并没有依赖于CPU的乱序执行(out-of-order),所以理论上该攻击算法同样适用于顺序执行(in-order)的处理器; 5.1.2攻击函数 让我们考虑如下的...
换而言之,如果在Linux下用一般的GCC编译器对程序进行编译,即可实施Spectre V1攻击。 于是,通过运行Github上的spectre-attack程序来查看受害者程序是否真的能够被Spectre V1攻击窃取一些秘密信息: 对受害者程序进行Spectre V1攻击 至此,确认Spectre V1攻击在Linux下可以被实施,接下来将通过具体的程序实施Spectre V1攻击...

ARM: spectre-v1: fix syscall entry Browse files Prevent speculation at the syscall table decoding by clamping the index used to zero on invalid system call numbers, and using the csdb speculative barrier. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Acked-by: Mark Rutland ...
Red Hat has been made aware of a new subvariant of the Spectre v1 class of vulnerabilities disclosed earlier this year. As with the earlier vulnerabilities, this industry-wide vulnerability exists in many microprocessors that implement speculative execution of instructions. Mitigation requires updates ...
