CVE-2021-47226

CVE-2021-47226 describes a Linux kernel issue where an XRSTOR on a user-buffered FPU state could fail with a page fault yet modify the destination task’s FPU state. The root cause is that during __fpu__restore_sig(), XRSTOR could run with preserved registers for a different task (fpu_fpregs_owner...
