CVE-2026-64167

VendorlinuxProductlinux kernelDiscoveredJul 19, 2026UpdatedAug 13, 2026

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+... fdt_check_node_offset_+... fdt_first_property_offset+... fdt_get_property_namelen_+... fdt_getprop+... kho_memory_init+... mm_core_init+... start_kernel+... kho_locate_mem_hole() already skips KHO logic for KEXEC_TYPE_CRASH images, but…
