Vulnerability from github – Published: 2025-12-16 15:30 – Updated: 2026-07-30 06:32In the Linux kernel, the following vulnerability has been resolved:
spi: rockchip-sfc: Fix DMA-API usage
Use DMA-API dma_map_single() call for getting the DMA address of the transfer buffer instead of hacking with virt_to_phys().
This fixes the following DMA-API debug warning: ------------[ cut here ]------------ DMA-API: rockchip-sfc fe300000.spi: device driver tries to sync DMA memory it has not allocated [device address=0x000000000cf70000] [size=288 bytes] WARNING: kernel/dma/debug.c:1106 at check_sync+0x1d8/0x690, CPU#2: systemd-udevd/151 Modules linked in: ...
