Description

This security bulletin contains information about 1 security vulnerability.


1) Empty Exception Block (CVE-ID: CVE-2026-23295)

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a deadlock condition in the AMDXDNA driver when handling IOCTL queries during device suspend and resume operations. A local user can issue a specially crafted IOCTL request during an auto-suspend cycle to trigger a deadlock, resulting in a denial of service.

The system must be in the process of suspending or resuming, and the attacker must have access to the device interface.
