Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 6.12.94/6.18.36/7.0.13/7.1.1. Affected is an unknown code of the component ADC. The manipulation of the argument ADS1298_MASK_CH_PGA with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2026-53386 since 06/09/2026. The exploitability is told to be easy. Local access is required to approach this attack. Additional levels of successful authentication are necessary for exploitation. Technical details are known, but there is no available exploit.

Upgrading to version 6.12.95, 6.18.37, 7.0.14, 7.1.2 or 7.2-rc1 eliminates this vulnerability.
