FKIE_CVE-2022-50055
Vulnerability from fkie_nvd - Published: 2025-06-18 11:15 - Updated: 2026-06-17 05:22
Severity
Summary
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]
