Bottlerocket: kernel-6.1: security update to 2.9.1

high Tenable Cloud Security Plugin ID 428070

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: VMCI: Fix use-after-free when removing
resource in vmci_resource_remove() When removing a resource from vmci_resource_table in
vmci_resource_remove(), the search is performed using the resource handle by comparing context and
resource fields. It is possible though to create two resources with different types but same handle (same
context and resource fields). When trying to remove one of the resources, vmci_resource_remove() may not
remove the intended one, but the object will still be freed as in the case of the datagram type in
vmci_datagram_destroy_handle(). vmci_resource_table will still hold a pointer to this freed resource
leading to a use-after-free vulnerability. BUG: KASAN: use-after-free in vmci_handle_is_equal
