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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
