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.
