CBL Mariner 2.0 Security Update: kernel (CVE-2024-47684)

medium Nessus Plugin ID 212970

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-47684 advisory.

 - In the Linux kernel, the following vulnerability has been resolved: tcp: check skb is non-NULL in tcp_rto_delta_us() We have some machines running stock Ubuntu 20.04.6 which is their 5.4.0-174-generic kernel that are running ceph and recently hit a null ptr dereference in tcp_rearm_rto(). Initially hitting it from the TLP path, but then later we also saw it getting hit from the RACK case as well. Here are examples of the oops messages we saw in each of those cases: July 26 15:05:02 rx [11061395.780353] BUG:
