CVE-2026-74698

This vulnerability affects the mlx5e network driver in the Linux kernel (used by Mellanox/NVIDIA ConnectX NICs). The root cause is that mlx5e_activate_txqsq() unconditionally calls netdev_tx_reset_queue(), which zeroes BQL (Byte Queue Limits) counters on channels that still have in-flight TX WQEs...
