Echo: linux: security update to 6.1.140-1

high Tenable Self-Hosted Container Security Plugin ID 461134

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: qfq: 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 qfq, there won't be a
 UAF, but the code will add the same classifier to the list twice, which will cause memory corruption. This
 patch checks whether the class was already added to the agg->active list (cl_is_active) before doing the
 addition to cater for the reentrant case. [1]
