In the Linux kernel, the following vulnerability has been resolved:

xsk: require at least 16 bytes of TX metadata

AF_XDP accepts a TX metadata length as small as eight bytes, but every

supported request needs the flags plus at least one eight-byte request

field. Such short metadata also lets the kernel read beyond the registered

area.

Require 16 bytes rather than sizeof(struct xsk_tx_metadata) to preserve

compatibility with applications that do not use launch-time metadata. (NVD)
