CVE-2022-49610 KVM: VMX: Prevent RSB underflow before vmenter

In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Prevent RSB underflow before vmenter On VMX, there are some balanced returns between the time the guest's SPECCTRL value is written, and the vmenter. Balanced returns matched by a preceding call are usually ok, but it's...

The vulnerability of Xen hypervisors relates to insufficient validation of input data, allowing attackers to trigger a service failure.

The vulnerability of Xen hypervisors is related to an error in the VMX VMEntry function, which does not handle certain cases correctly. Exploiting this vulnerability can allow a remote attacker to cause service interruptions...
