CVE-2025-68238 mtd: rawnand: cadence: fix DMA device NULL pointer dereference

In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: fix DMA device NULL pointer dereference The DMA device pointer dmadev was being dereferenced before ensuring that cdnsctrl-dmac is properly initialized. Move the assignment of dmadev after successfully...

CVE-2025-68238

CVE-2025-68238 affects the Linux kernel mtd: rawnand: cadence driver. Root cause: the DMA device pointer (dma_dev) was dereferenced before cdns_ctrl->dmac was initialized, risking NULL dereference. Fix: move the assignment of dma_dev to after successfully acquiring the DMA channel, ensuring th...

CVE-2025-40356 spi: rockchip-sfc: Fix DMA-API usage

In the Linux kernel, the following vulnerability has been resolved: spi: rockchip-sfc: Fix DMA-API usage Use DMA-API dmamapsingle call for getting the DMA address of the transfer buffer instead of hacking with virttophys. This fixes the following DMA-API debug warning: ------------ cut here...

CVE-2025-40356

CVE-2025-40356 affects the Linux kernel driver rockchip_sfc (SPI rockchip-sfc). The underlying issue was incorrect use of the DMA-API: the driver used virt_to_phys() to obtain the DMA address of the transfer buffer instead of dma_map_single(), which caused a DMA memory sync warning. The vulnerabi...
