Type Values Removed Values Added
Description In the Linux kernel, the following vulnerability has been resolved: xen/netback: Fix buffer overrun triggered by unusual packet It is possible that a guest can send a packet that contains a head + 18 slots and yet has a len <= XEN_NETBACK_TX_COPY_LEN. This causes nr_slots to underflow in xenvif_get_requests() which then causes the subsequent loop's termination condition to be wrong, causing a buffer overrun of queue->tx_map_ops. Rework the code to account for the extra frag_overflow slots. This is CVE-2023-34319 / XSA-432. This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
