Description

This security bulletin contains information about 1 vulnerability.


1) Off-by-one (CVE-ID: CVE-2026-98835)

CWE-ID: CWE-193 - Off-by-one Error

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause an out-of-bounds read that may disclose kernel memory or cause a denial of service.

The vulnerability exists due to an off-by-one array bounds check in the Linux kernel Kionix KX022A accelerometer driver's kx022a_read_raw() function when converting a register value into a sampling-frequency table index. A local user can trigger an out-of-bounds read if the masked register value equals the number of table entries, potentially disclosing kernel memory or causing a denial of service.
