Description
This security bulletin contains information about 1 vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2026-64495)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to out-of-bounds read in bmg160_get_filter() and bmg160_set_filter() when handling sysfs input for the in_anglvel_filter_low_pass_3db_frequency interface. A local user can supply a value that is not present in bmg160_samp_freq_table to cause a denial of service.
The issue is reachable from userspace through the sysfs interface.
