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-2024-50163 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Make sure internal and UAPI     bpf_redirect flags don't overlap The bpf_redirect_info is shared between the SKB and XDP redirect paths,     and the two paths use the same numeric flag values in the ri->flags field (specifically, BPF_F_BROADCAST     == BPF_F_NEXTHOP). This means that if skb bpf_redirect_neigh() is used with a non-NULL params argument     and, subsequently, an XDP redirect is performed using the same bpf_redirect_info struct, the XDP path will     get confused and end up crashing, which syzbot managed to trigger. With the stack-allocated     bpf_redirect_info, the structure is no longer shared between the SKB and XDP paths, so the crash doesn't     happen anymore. However, different code paths using identically-numbered flag values in the same struct     field still seems like a bit of a mess, so this patch cleans that up by moving the flag definitions     together and redefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlap with the flags used for     XDP. It also adds a BUILD_BUG_ON() check to make sure the overlap is not re-introduced by mistake.
    (CVE-2024-50163)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
