CBL Mariner 2.0 Security Update: hyperv-daemons (CVE-2023-5178)

critical Nessus Plugin ID 185992

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-2023-5178 advisory.

 - A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause a use-after-free and double-free problem, which may permit remote code execution or lead to local privilege escalation in case that the attacker already has local privileges. (CVE-2023-5178)

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.
