Technical description

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]

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
