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]

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
