# CVE-2026-64495

> 3.1 LOW

## Beschreibung

In the Linux kernel, the following vulnerability has been resolved:

iio: gyro: bmg160: bail out when bandwidth/filter is not in table

bmg160_get_filter() walks bmg160_samp_freq_table[] looking for the entry
matching the bw_bits value read from the chip:

	for (i = 0; i < ARRAY_SIZE(bmg160_samp_freq_table); ++i) {
		if (bmg160_samp_freq_table[i].bw_bits == bw_bits)
			break;
	}
	*val = bmg160_samp_freq_table[i].filter;

If no entry matches, i ends up equal to the array size and the next line
reads one slot past the end. bmg160_set_filter() has the same shape, driven
by 'val' instead of bw_bits.

smatch flags both:

  drivers/iio/gyro/bmg160_core.c:204 bmg160_get_filter() error:
  buffer overflow 'bmg160_samp_freq_table' 7
