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

by Sedat Dilek

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- https://xenbits.xen.org/xsa/advisory-466.html https://www.phoronix.com/news/Xen-XSA-466-Linux https://mirrors.edge.kernel.org/pub/tools/llvm/files/
