CVE-2026-64495
Estado: RecibidaSin puntuar—
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:
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:
Return -EINVAL when no entry matches.
The set_filter() path is reachable from userspace via the sysfs in_anglvel_filter_low_pass_3db_frequency interface, so userspace can trivially trigger the out-of-bounds read with a value that is not in bmg160_samp_freq_table[].filter.
