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...
