Description

In the Linux kernel, the following vulnerability has been resolved:  vdpa_sim_net: check TX pull result before RX copy  vringh_iov_pull_iotlb() returns a signed byte count.  A failed TX pull is currently added to the unsigned byte counter and then passed as a size_t length to receive_filter() and vringh_iov_push_iotlb().  A negative error can therefore become a large length in the RX path.  Handle non-positive pull results before every length use.  Count the TX error and complete the consumed TX descriptor with zero bytes.  I found this bug myself, though the patch was written with AI assistance.
