Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/fpu: KVM: Set the base guest FPU uABI size to sizeofstruct kvmxsave. The starting uABI size of KVM’s guest FPU was set to ‘struct kvmxsave’, which corresponds to KVM’s historical uABI size. When saving the FPU state for a use...

UBUNTU-CVE-2022-50425

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 ...

CVE-2022-50425

CVE-2022-50425 is a Linux kernel vulnerability in the x86/fpu path. The issue occurs in copy_xstate_to_uabi() when an extended state component exists in init_fpstate but not fpstate, causing a NULL pointer dereference during XSAVE state handling in KVM/KVM-related ioctl paths. The mitigation desc...
