CVE-2021-47227
In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Prevent state corruption in fpurestoresig The non-compacted slowpath uses copyfromuser and copies the entire user buffer into the kernel buffer, verbatim. This means that the kernel buffer may now contain entirely invali...

CVE-2021-47226 x86/fpu: Invalidate FPU state after a failed XRSTOR from a user buffer
In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Invalidate FPU state after a failed XRSTOR from a user buffer Both Intel and AMD consider it to be architecturally valid for XRSTOR to fail with PF but nonetheless change the register state. The actual conditions under...
kernel: x86/fpu: Fix copy_xstate_to_uabi() to copy init states correctly
In the Linux kernel, the following vulnerability has been resolved: x86/fpu: Fix copyxstatetouabi to copy init states correctly When an extended state component is not present in fpstate, but in init state, the function copies from initfpstate via copyfeature. But, dynamic states are not present ...
