Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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: <IRQ> 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->cc == sq->pc). In the
 case that reset is skipped, the outstanding WQEs will eventually complete and rebalance the dql. The
 dql->limit is carried across the reset. (CVE-2026-74698)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20085.0.0 or later.
