CVE-ID: CVE-2021-22040
CWE-ID:
CWE-416 - Use After Free
Exploit availability: No
DescriptionThe vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to a use-after-free error in the XHCI USB controller. A remote user with administrative permissions on the guest OS can trigger a use-after-free error and execute arbitrary code as the virtual machine's VMX process running on the host.
Successful exploitation of the vulnerability may allow an attacker to compromise the hypervisor.
Install updates from vendor's website.
