CBL Mariner 2.0 Security Update: hyperv-daemons (CVE-2024-27418)

medium Nessus Plugin ID 212164

Synopsis

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

Description

The version of hyperv-daemons 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-2024-27418 advisory.

 - In the Linux kernel, the following vulnerability has been resolved: net: mctp: take ownership of skb in mctp_local_output Currently, mctp_local_output only takes ownership of skb on success, and we May leak an skb if mctp_local_output fails in specific states; the skb ownership isn't transferred until the actual output routing occurs. Instead, make mctp_local_output free the skb on all error paths up to the route action, so it always consumes the passed skb. (CVE-2024-27418)

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.
