CVE-2026-64495: iio: gyro: bmg160: bail out when bandwidth/filter is not in table

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
  • Fixed version: Linux Linux 029481cddb98697716f4bf3021d035eaf2ca0e1f, 1dc3a833be11e5d503038e3c701745fd0e03903c, 6c8675468862161d1c59130266852b66867d3861.

Low priority for now. Upgrade to Linux Linux 029481cddb98697716f4bf3021d035eaf2ca0e1f, 1dc3a833be11e5d503038e3c701745fd0e03903c, 6c8675468862161d1c59130266852b66867d3861 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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: buffer overflow 'bmg160_samp_freq_table' 7 <= 7 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.
