  "description": "In the Linux kernel, the following vulnerability has been resolved:  kho: skip KHO for crash kernel  kho_fill_kimage() unconditionally populates the kimage with KHO metadata for every kexec image type. When the image is a crash kernel, this can be problematic as the crash kernel can run in a small reserved region and the KHO scratch areas can sit outside it. The crash kernel then faults during kho_memory_init() when it tries phys_to_virt() on the KHO FDT address:    Unable to handle kernel paging request at virtual address xxxxxxxx   ...     fdt_offset_ptr\u002B...     fdt_check_node_offset_\u002B...     fdt_first_property_offset\u002B...     fdt_get_property_namelen_\u002B...     fdt_getprop\u002B...     kho_memory_init\u002B...     mm_core_init\u002B...     start_kernel\u002B...  kho_locate_mem_hole() already skips KHO logic for KEXEC_TYPE_CRASH images, but kho_fill_kimage() was missing the same guard. As kho_fill_kimage() is the single point that populates image-\u003Ekho.fdt and image-\u003Ekho.scratch, fixing it here is sufficient for both arm64 and x86 as the FDT and boot_params path are bailing out when these fields are unset.",
