CVE-2026-53386 Details
Description
In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-ads1298: add bounds check to pga_settings index ads1298_pga_settings has 7 elements but ADS1298_MASK_CH_PGA can yield values 0-7. If it yields a value >= 7, this causes an out-of-bounds array access. Add a bounds check and return -EINVAL if the index is out of range. Note that the remaining value b111 is reserved so should not be seen in a correctly functioning system.
A vulnerability in the Linux kernel's IIO ADC driver for the TI ADS1298 has been addressed. The issue arose because the 'ads1298_pga_settings' array, which contains 7 elements, could be accessed out-of-bounds. The 'ADS1298_MASK_CH_PGA' mask can produce values from 0 to 7, and values of 7 or higher lead to invalid array access. The vulnerability has been fixed by adding a bounds check that returns an error if the index is out of range.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. The specific commit addressing this issue is available in the Linux kernel stable tree.
