Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992559)

medium Nessus Plugin ID 280439

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-2025-992559 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 iavf: Fix adminq error handling

 iavf_alloc_asq_bufs/iavf_alloc_arq_bufs allocates with dma_alloc_coherent memory for VF mailbox.
 Free DMA regions for both ASQ and ARQ in case error happens during configuration of ASQ/ARQ registers.
 Without this change it is possible to see when unloading interface:
 74626.583369: dma_debug_device_change: device driver has pending DMA allocations while released from device [count=32] One of leaked entries details: [device address=0x0000000b27ff9000] [size=4096 bytes] [mapped with DMA_BIDIRECTIONAL] [mapped as coherent]

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.

Solution

Update the affected kernel package.
