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 <= 7 drivers/iio/gyro/bmg160_core.c:222 bmg160_set_filter() error
Add your gear to cvedb and we'll alert you only when a vendor you run ships something exploited.
