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...

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 ...

SUSE CVE-2013-1442

Xen 4.0 through 4.3.x, when using AVX or LWP capable CPUs, does not properly clear previous data from registers when using an XSAVE or XRSTOR to extend the state components of a saved or restored vCPU after touching other restored extended registers, which allows local guest OSes to obtain...

SUSE CVE-2015-2672

The xsave/xrstor implementation in arch/x86/include/asm/xsave.h in the Linux kernel before 3.19.2 creates certain .altinstrreplacement pointers and consequently does not provide any protection against instruction faulting, which allows local users to cause a denial of service panic by triggering ...
