CVE-2025-0005 Overview
CVE-2025-0005 is an integer overflow vulnerability in the AMD XOCL driver caused by improper input validation. A local attacker with low privileges can trigger the overflow condition through crafted input to the driver interface. Successful exploitation can crash the affected system or produce a denial of service state. The flaw is tracked as CWE-190: Integer Overflow or Wraparound. AMD documented the issue in AMD Security Bulletin #8014.
Critical Impact
Local attackers can trigger an integer overflow in the XOCL driver to crash systems or cause denial of service on affected AMD platforms.
Affected Products
- AMD XOCL driver (see vendor advisory for affected product list)
- AMD adaptive computing platforms using the XOCL kernel driver

Technical Details for CVE-2025-0005
Vulnerability Analysis
The XOCL driver fails to properly validate numeric input received from local user-mode callers. When unchecked values participate in arithmetic operations such as size calculations or buffer length computations, the result wraps around the integer boundary. This produces values that no longer reflect the original intent of the calculation.
Downstream code paths then operate on the wrapped value, leading to inconsistent driver state, invalid memory operations, or kernel-level faults. The end result observed by AMD is a crash of the driver or the host system, yielding a denial of service condition. Because the affected component is a kernel driver, the impact extends to overall system availability rather than a single user session.
Root Cause
The root cause is missing or insufficient bounds checking on attacker-controlled integer values prior to arithmetic operations [CWE-190]. The driver accepts inputs that, when multiplied or added, exceed the storage capacity of the integer type. The truncated result bypasses subsequent length and range checks, producing inconsistent state that the kernel cannot safely recover from.
Attack Vector
Exploitation requires local access to the system running a vulnerable XOCL driver. The attacker does not need prior authentication to the driver interface but must be able to issue requests to the device. Crafted input is delivered through the driver's user-mode interface, such as ioctl calls or device file operations. No user interaction is required beyond the attacker's own actions.
The vulnerability mechanism is documented at a high level in AMD Security Bulletin #8014. No public proof-of-concept exploit code is currently available, and the issue is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-0005
Indicators of Compromise
- Unexpected kernel panics, bug checks, or system reboots on hosts running the AMD XOCL driver
- Repeated process crashes or service interruptions tied to XOCL device interactions
- Anomalous ioctl call patterns or unusually large size parameters issued to the XOCL device by non-administrative users
Detection Strategies
- Monitor kernel logs and crash dumps for faults referencing the XOCL driver module
- Correlate local user activity with driver crash events to identify potential exploitation attempts
- Track loaded driver versions across the fleet and flag hosts running pre-patch XOCL builds
Monitoring Recommendations
- Enable persistent kernel crash dump collection on systems with AMD adaptive computing hardware
- Forward driver fault telemetry and Windows Event Log or Linux dmesg output to a central SIEM
- Alert on repeated unexpected reboots of the same host within short time windows
How to Mitigate CVE-2025-0005
Immediate Actions Required
- Inventory all systems running the AMD XOCL driver and identify their current driver versions
- Apply the updated XOCL driver release referenced in AMD Security Bulletin #8014
- Restrict local access to systems hosting the affected driver until patches are deployed
Patch Information
AMD has published remediation guidance in AMD Security Bulletin #8014. Administrators should consult the bulletin for the specific fixed driver versions and apply them according to the vendor's deployment instructions.
Workarounds
- Limit shell and interactive access on affected hosts to trusted administrative users only
- Apply strict file permissions on the XOCL device node to prevent unprivileged users from issuing ioctl requests
- Where the driver is not required for operations, unload or disable the XOCL module until the patch is applied
