Bottlerocket: kernel-6.1: security update to 2.9.1

medium Tenable Cloud Security Plugin ID 428032

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: tcp_bpf: fix return value of
tcp_bpf_sendmsg() When we cork messages in psock->cork, the last message triggers the flushing will result
in sending a sk_msg larger than the current message size. In this case, in tcp_bpf_send_verdict(),
'copied' becomes negative at least in the following case: 468 case __SK_DROP: 469 default: 470
sk_msg_free_partial(sk, msg, tosend); 471 sk_msg_apply_bytes(psock, tosend); 472 *copied -= (tosend +
delta); // <==== HERE 473 return -EACCES; Therefore, it could lead to the following BUG with a proper
value of 'copied' (thanks to syzbot). We should not use negative 'copied' as a return value here.
