Vulnerability overview
In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: reject a command chain that carries no commands A chain whose command_count is zero passes the payload length check, because struct_size(payload, data, 0) is just the header. The fill loop then does not run, so offset stays zero and the request is submitted with a zero-length buffer. On firmware without AIE2_NPU_COMMAND that ends at the opcode check, since op is still ERT_INVALID_CMD and aie2_get_chain_msg_op() answers MSG_OP_MAX_OPCODE. aie2_get_npu_chain_msg_op() answers MSG_OP_CHAIN_EXEC_NPU whatever it is given, so there the submission continues to drm_clflush_virt_range(cmd_buf, 0), which reads the byte before the buffer and faults on the vmap guard page. EXEC_CMD is reachable by any process that can open the render node. Reject the request instead.
