CBL Mariner 2.0 Security Update: hyperv-daemons (CVE-2023-6121)

medium Nessus Plugin ID 202361

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-2023-6121 advisory.

 - An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue May allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).
 (CVE-2023-6121)

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.
