Hi, Please note that with the update to kernel 5.12, we now have a kernel-debug package for aarch64. This kernel-debug package includes MTE (Heap) in-kernel support with CONFIG_KASAN_HW_TAGS enabled. On supported hardware (or in qemu), you will get the following lines in the kernel log: [ 0.000000] CPU features: detected: Memory Tagging Extension [ 0.000000] kasan: KernelAddressSanitizer initialized More information at https://en.opensuse.org/Arm_architecture_support#In-kernel_support Thanks, Guillaume
