Summary

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: tighten bounds checking in decode_message() Copy the bounds checking from encode_message() to decode_message(). This patch addresses the following concerns. Ensure that there is enough space for at least one header so that we don't have a negative size later. if (msg_hdr_len < sizeof(*trans_hdr)) Ensure that we have enough space to read the next header from the msg->data. if (msg_len > msg_hdr_len - sizeof(*trans_hdr)) return -EINVAL; Check that the trans_hdr->len is not below the minimum size: if (hdr_len < sizeof(*trans_hdr)) This minimum check ensures that we don't corrupt memory in decode_passthrough() when we do. memcpy(out_trans->data, in_trans->data, len - sizeof(in_trans->hdr)); And fi
