CVE-2022-49610 is a Linux kernel KVM VMX protection-mechanism flaw involving the interval after the guest SPEC_CTRL value is written and before virtual-machine entry. Balanced return instructions in that interval could theoretically be reached after an NMI with a sufficiently deep call stack empties the Return Stack Buffer (RSB), causing an RSB underflow. The fix eliminates all returns, including balanced returns, between the SPEC_CTRL write and VM entry.
