Echo: linux: security update to 6.1.140-1

high Tenable Cloud Security Plugin ID 463065

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_sched: drr: Fix double list add in
 class with netem as child qdisc As described in Gerrard's report [1], there are use cases where a netem
 child qdisc will make the parent qdisc's enqueue callback reentrant. In the case of drr, there won't be a
 UAF, but the code will add the same classifier to the list twice, which will cause memory corruption. In
 addition to checking for qlen being zero, this patch checks whether the class was already added to the
 active_list (cl_is_active) before adding to the list to cover for the reentrant case. [1]
