  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nriscv: Prevent NULL pointer dereference in machine_kexec_prepare()\n\nA NULL pointer dereference issue is noticed in riscv's\nmachine_kexec_prepare(), where image->segment[i].buf might be NULL and\ncopied unchecked.\n\nThe NULL buf comes from ima_add_kexec_buffer(), where kbuf is added by\nkexec_add_buffer(), but kbuf.buffer is NULL, then it is copied without\na check in machine_kexec_prepare():\n\n  kexec_file_load\n    -> kimage_file_alloc_init()\n       -> kimage_file_prepare_segments()\n          -> ima_add_kexec_buffer()\n             -> kexec_add_buffer()\n    -> machine_kexec_prepare()\n       -> memcpy()\n\nAddress this by adding a check before the data copy attempt.",
