Linux Distros 未修補的弱點:CVE-2022-49338

medium Nessus Plugin ID 245595

概要

Linux/Unix 主機上安裝的一個或多個套件存有弱點,供應商表示將不會修補。

說明

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件,且供應商未提供可用的修補程式。

- 已解決 Linux 核心中的下列弱點:net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules CT cleanup assumes that all tc rules were deleted first, and so is free to delete the CT shared resources (e.g the dr_action fwd_action which is shared for all tuples). But currently for uplink, this is happens in reverse, causing the below trace. CT cleanup is called from:
mlx5e_cleanup_rep_tx()->mlx5e_cleanup_uplink_rep_tx()-> mlx5e_rep_tc_cleanup()->mlx5e_tc_esw_cleanup()-> mlx5_tc_ct_clean() Only afterwards, tc cleanup is called from:
mlx5e_cleanup_rep_tx()->mlx5e_tc_ht_cleanup() which would have deleted all the tc ct rules, and so delete all the offloaded tuples. Fix this reversing the order of init and on cleanup, which will result in tc cleanup then ct cleanup.
