CVE-2026-31768

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ti-adc161s626 component of the Industrial I/O (IIO) ADC subsystem where spi read() utilized stack memory instead of DMA-safe memory. Direct Memory Access (DMA) is a feature that allows hardware subsystems to access main system memory independently of the central processing unit. All SPI buffers are required to be DMA-safe to ensure system stability and correctness.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
