FreeBSD : FreeBSD -- arm64 boot CPUs may lack speculative execution protections (162a675b-6251-11ee-8e38-002590c1f29c)

medium Nessus Plugin ID 182476

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 162a675b-6251-11ee-8e38-002590c1f29c advisory.

 - On CPU 0 the check for the SMCCC workaround is called before SMCCC support has been initialized. This resulted in no speculative execution workarounds being installed on CPU 0. (CVE-2023-5370)

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.
