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: Wrap the tx reporter dump
 callback to extract the sq Function mlx5e_tx_reporter_dump_sq() casts its void * argument to struct
 mlx5e_txqsq *, but in TX-timeout-recovery flow the argument is actually of type struct
 mlx5e_tx_timeout_ctx *. mlx5_core 0000:08:00.1 enp8s0f1: TX timeout detected mlx5_core 0000:08:00.1
