- Summary
- iio: adc: ti-adc161s626: use DMA-safe memory for spi_read()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ti-adc161s626: use DMA-safe memory for spi_read()
Add a DMA-safe buffer and use it for spi_read() instead of a stack memory. All SPI buffers must be DMA-safe.
Since we only need up to 3 bytes, we just use a u8[] instead of __be16 and __be32 and change the conversion functions appropriately.
