CVE-2026-31505

The CVE-2026-31505 issue affects the Linux kernel iavf driver: out-of-bounds writes occur because iavf_get_ethtool_stats() uses real_num_tx_queues for ETH_SS_STATS while other paths use num_tx_queues, enabling memory corruption when ethtool -L and ethtool -S run concurrently. The fix is to use im...
