  "description": "In the Linux kernel, the following vulnerability has been resolved:  riscv: Prevent NULL pointer dereference in machine_kexec_prepare()  A NULL pointer dereference issue is noticed in riscv\u0027s machine_kexec_prepare(), where image-\u003Esegment[i].buf might be NULL and copied unchecked.  The NULL buf comes from ima_add_kexec_buffer(), where kbuf is added by kexec_add_buffer(), but kbuf.buffer is NULL, then it is copied without a check in machine_kexec_prepare():    kexec_file_load     -\u003E kimage_file_alloc_init()        -\u003E kimage_file_prepare_segments()           -\u003E ima_add_kexec_buffer()              -\u003E kexec_add_buffer()     -\u003E machine_kexec_prepare()        -\u003E memcpy()  Address this by adding a check before the data copy attempt.",
