CVE-2026-99079

A flaw was found in the Linux kernel's Mellanox network driver (mlx5e). When network traffic redirected to an AF_XDP (eXpress Data Path) socket encounters a full receive ring and buffer refills only partially succeed, the driver retains a stale buffer reference. A remote attacker could exploit this condition by sending high volumes of network traffic, causing the driver to prematurely free active memory buffers during refill retries. This issue can lead to memory corruption or a Denial of Service (DoS).
