Bottlerocket: bottlerocket-kernel-5.15, kernel-5.15: security update to 5.15.184

high Tenable Cloud Security Plugin ID 428224

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: ets: 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 ets, 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 doing the addition to cater for the reentrant case. [1]
