CVE-2026-43461

HIGHNVD 7.87.8—

7.8

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

spi: amlogic: spifc-a4: Fix DMA mapping error handling

Fix three bugs in aml_sfc_dma_buffer_setup() error paths:

Unnecessary goto: When the first DMA mapping (sfc->daddr) fails,

nothing needs cleanup. Use direct return instead of goto.

Double-unmap bug: When info DMA mapping failed, the code would

unmap sfc->daddr inline, then fall through to out_map_data which would unmap it again, causing a double-unmap.

Wrong unmap size: The out_map_info label used datalen instead of

infolen when unmapping sfc->iaddr, which could lead to incorrect DMA sync behavior.

CVSS v3: 7.8
EG Score: 7.8(high)
EPSS: 2.3%
KEV: Not listed
