  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nxsk: require at least 16 bytes of TX metadata\n\nAF_XDP accepts a TX metadata length as small as eight bytes, but every\nsupported request needs the flags plus at least one eight-byte request\nfield. Such short metadata also lets the kernel read beyond the registered\narea.\n\nRequire 16 bytes rather than sizeof(struct xsk_tx_metadata) to preserve\ncompatibility with applications that do not use launch-time metadata.",
