In the Linux kernel, the following vulnerability has been resolved: iio: accel: kionix-kx022a: Fix array boundary check The driver performs a sanity… (CVE-2026-98835)

The Linux kernel's kionix-kx022a accelerometer driver performed a sanity check on an array index derived from a register value. The check incorrectly allowed the index to be equal to the size of the array, which is invalid since array indices are zero-based and the last valid index is size minus one. This off-by-one error could lead to out-of-bounds access. The vulnerability was resolved by modifying the check to bail out when the index is greater than or equal to the array size.

The vulnerability could cause the driver to access memory outside the bounds of the array, potentially leading to undefined behavior such as crashes or memory corruption. No specific exploitation details or impacts such as privilege escalation or code execution are provided.

A fix has been applied to the Linux kernel to correct the array boundary check in the kionix-kx022a driver. Users should update to a kernel version that includes this fix. No additional mitigation steps are indicated.
