CVE-2023-54172 x86/hyperv: Disable IBT when hypercall page lacks ENDBR instruction

In the Linux kernel, the following vulnerability has been resolved: x86/hyperv: Disable IBT when hypercall page lacks ENDBR instruction On hardware that supports Indirect Branch Tracking IBT, Hyper-V VMs with ConfigVersion 9.3 or later support IBT in the guest. However, current versions of Hyper-...

CVE-2023-54172

CVE-2023-54172 affects the Linux kernel's x86/hyperv integration. The vulnerability arose because Hyper-V VMs with ConfigVersion 9.3+ support IBT in the guest, but the hypercall page could be missing ENDBR64. Since hypercalls use an indirect call to the hypercall page, this caused an exception an...
