CVE-2023-34319

The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a way such that not all of the headers would come in one piece. Unfortunately the logic introduced there didn't account for the extreme case of the entire packet being split into as many piece...

CVE-2023-34319 Linux: buffer overrun in netback due to unusual packet

CVE-2023-34319

CVE-2023-34319 is a Linux kernel netback driver buffer overrun caused by an edge case where an entire packet is fragmented into the maximum pieces yet remains smaller than the area that preserves all headers together, after the XSA-423 fix. Exploitation could enable local denial-of-service or ins...
