CVE-2025-32776 | OpenRazer Vulnerable to Out of Bounds Read

OpenRazer is an open source driver and user-space daemon to control Razer device lighting and other features on GNU/Linux. By writing specially crafted data to the `matrix_custom_frame` file, an attacker can cause the custom kernel driver to read more bytes than provided by user space. This data will be written into the RGB arguments which will be sent to the USB device. This issue has been patched in v3.10.2.

5.5 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
