[Linux-6.12.y] XEN: CVE-2024-53241 / XSA-466 and Clang-kCFI

Hi,

Linux v6.12.6 will include XEN CVE fixes from mainline.

Here, I use Debian/unstable AMD64 and the SLIM LLVM toolchain 19.1.x from kernel.org.

What does it mean in ISSUE DESCRIPTION...

Furthermore, the hypercall page has no provision for Control-flow Integrity schemes (e.g. kCFI/CET-IBT/FineIBT), and will simply malfunction in such configurations.

...when someone uses Clang-kCFI?

My full kernel-config is attached.

Thanks in advance.

Best regards, -Sedat-
