medium Nessus Plugin ID 272394
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990194 advisory.In the Linux kernel, the following vulnerability has been resolved:
mips: bmips: BCM6358: make sure CBR is correctly set
It was discovered that some device have CBR address set to 0 causing kernel panic when arch_sync_dma_for_cpu_all is called.
This was notice in situation where the system is booted from TP1 and BMIPS_GET_CBR() returns 0 instead of a valid address and !!(read_c0_brcm_cmt_local() & (1 << 31)); not failing.
The current check whether RAC flush should be disabled or not are not enough hence lets check if CBR is a valid address or not.
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
