Bottlerocket: kernel-5.15, kernel-6.1: security update to 2.4.0

high Tenable Cloud Security Plugin ID 427977

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: vhost/vsock: always initialize
seqpacket_allow There are two issues around seqpacket_allow: 1. seqpacket_allow is not initialized when
socket is created. Thus if features are never set, it will be read uninitialized. 2. if
VIRTIO_VSOCK_F_SEQPACKET is set and then cleared, then seqpacket_allow will not be cleared appropriately
(existing apps I know about don't usually do this but it's legal and there's no way to be sure no one
relies on this). To fix: - initialize seqpacket_allow after allocation - set it unconditionally in
set_features (CVE-2024-43873)
