Description
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: check for nEPT/nNPT in slow flush hypercalls
Checking is_guest_mode(vcpu) is incorrect, because translate_nested_gpa()
is only valid if an L2 guest is running *with nested EPT/NPT enabled*.
Instead use the same condition as translate_nested_gpa() itself.
Affected configurations
• linux linux kernel (>= 6.2 < 6.6.140)
• linux linux kernel (>= 6.7 < 6.12.88)
• linux linux kernel (>= 6.13 < 6.18.30)
• linux linux kernel (>= 6.19 < 7.0.7)
• linux linux kernel 7.1
