CVE-2026-64495

Local kernel-data disclosure via unmatched filter lookup

Published Jul 25, 2026 · Updated Jul 25, 2026

Out-of-bounds read in the Linux Kernel BMG160 gyroscope driver allows local users to disclose adjacent kernel data through sysfs. bmg160_set_filter() scans bmg160_samp_freq_table for a requested filter value and dereferences the array-size index when no entry matches. Reachability requires the BMG160 driver and access to its in_anglvel_filter_low_pass_3db_frequency sysfs attribute; the reported consequence is limited to a local kernel-data read.
