Vulnerability Title
x86/xen: don't do PV iret hypercall through hypercall page
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: x86/xen: don't do PV iret hypercall through hypercall page Instead of jumping to the Xen hypercall page for doing the iret hypercall, directly code the required sequence in xen-asm.S. This is done in preparation of no longer using hypercall page at all, as it has shown to cause problems with speculation mitigations. This is part of XSA-466 / CVE-2024-53241.
