Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已被修复： net/mlx5: HWS，处理带有缺省跳转表（miss table）的表销毁问题 如果一个表通过 API 函数创建了对应的缺省跳转表（miss table），则该缺省跳转表（miss_tbl）会在其链表中保存指向该表的指针。 若删除此类表时未同时将其从缺省跳转表的链表中移除，则链表中的节点将包含无效数据（垃圾数据）。

Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: net/mlx5: HWS, Handle destroying table that has a miss table If a table has a miss table that was created by 'mlx5hws_table_set_default_miss' API function, its miss_tbl keeps the table that points to it in a list.
