Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds write (CVE-ID: CVE-2026-64273)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: 5.2 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an attacker with physical access to corrupt kernel memory.

The vulnerability exists due to an out-of-bounds write in iforce_process_packet() when processing a device-reported force-feedback status packet. An attacker with physical access can supply a crafted device payload with an out-of-range effect index to corrupt kernel memory.

The issue affects both USB interrupt endpoint and serio transports, and the status handling path is not gated on force-feedback support being present.
