Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xsk: require at least 16 bytes of TX metadata<br /> <br /> AF_XDP accepts a TX metadata length as small as eight bytes, but every<br /> supported request needs the flags plus at least one eight-byte request<br /> field. Such short metadata also lets the kernel read beyond the registered<br /> area.<br /> <br /> Require 16 bytes rather than sizeof(struct xsk_tx_metadata) to preserve<br /> compatibility with applications that do not use launch-time metadata.
