  "details": "In the Linux kernel, the following vulnerability has been resolved:  net/mlx5e: fix BQL reset on SQ re-activation  mlx5e_queue_start() deactivates and re-activates all channels but closes only the queue being restarted. mlx5e_activate_txqsq() then unconditionally calls netdev_tx_reset_queue(), zeroing the BQL counters of channels that kept their in-flight TX WQEs. The next completion then over-charges and trips the BUG_ON() in dql_completed():    kernel BUG at lib/dynamic_queue_limits.c:99!   RIP: 0010:dql_completed+0x23d/0x280   Call Trace:    \u003cIRQ\u003e    mlx5e_poll_tx_cq+0x668/0xa60    mlx5e_napi_poll+0x5b/0x7b0    net_rx_action+0x15a/0x580  Reset BQL only when the SQ has no bytes in flight (sq-\u003ecc == sq-\u003epc).  In the case that reset is skipped, the outstanding WQEs will eventually complete and rebalance the dql. The dql-\u003elimit is carried across the reset.",
