CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's AF_XDP implementation, where it improperly accepts transmit (TX) metadata lengths as small as eight bytes, potentially allowing the kernel to read beyond the allocated memory area. This could lead to memory corruption or information leakage, impacting system stability and security. Organizations using Linux kernel versions with this flaw should prioritize patching to mitigate potential exploitation risks.
Original NVD Description
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.
