CBL Mariner 2.0 Security Update: hyperv-daemons / kernel (CVE-2024-27015)

medium Nessus Plugin ID 206363

Synopsis

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

Description

The version of hyperv-daemons / 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-2024-27015 advisory.

 - In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: incorrect pppoe tuple pppoe traffic reaching ingress path does not match the flowtable entry because the pppoe header is expected to be at the network header offset. This bug causes a mismatch in the flow table lookup, so pppoe packets enter the classical forwarding path. (CVE-2024-27015)

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

Solution

Update the affected packages.
