In the Linux kernel, the following vulnerability has been resolved: iio: adc: ti-ads1298: add bounds check to pga_settings index… (CVE-2026-53386)
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.
AI Analysis
Technical Summary
The Linux kernel's iio adc ti-ads1298 driver contained a vulnerability where the ads1298_pga_settings array, which has 7 elements, could be accessed out-of-bounds due to the ADS1298_MASK_CH_PGA mask yielding values from 0 to 7. If the value was 7, this caused an out-of-bounds array access. The vulnerability was resolved by adding a bounds check on the pga_settings index and returning -EINVAL if the index is invalid. The reserved value b111 (7) should not normally appear in a correctly functioning system.
Potential Impact
An out-of-bounds array access can lead to undefined behavior including potential kernel crashes or memory corruption. However, the reserved value causing the out-of-bounds access should not occur in normal operation, which may limit exploitability. No known exploits are reported in the wild.
Mitigation Recommendations
A fix has been applied to the Linux kernel by adding a bounds check to the pga_settings index in the ti-ads1298 driver. Users should update to a kernel version that includes this fix. Patch status is not explicitly confirmed in the provided data; check the official Linux kernel advisories or vendor updates for the exact fixed versions and apply updates accordingly.
