Description
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.
Affected configurations
• linux linux kernel (>= 4.9 < 6.1.168)
• linux linux kernel (>= 6.2 < 6.6.134)
• linux linux kernel (>= 6.7 < 6.12.81)
• linux linux kernel (>= 6.13 < 6.18.22)
• linux linux kernel (>= 6.19 < 6.19.12)
