Analysis

Impact

A defect in the Linux kernel media driver wave5 causes the system to panic when the driver is closed. The driver initiates a suspend transition due to an autosuspend delay timeout, which generates an asynchronous SError interrupt that is not handled correctly, culminating in a kernel panic. The result is a complete system crash, making the service unavailable and potentially affecting all users on the affected host.

Affected Systems

Vendors: Linux. Products: Any Linux kernel that includes the wave5 driver for Teledyne/Texas Instruments J721S2 EVM. The issue was observed in kernel 6.12.9, so earlier kernel releases containing that driver are likely impacted.

Risk and Exploitability

The vulnerability manifests locally and can be triggered by running a V4L2 H265 decode task that closes the driver. Being a kernel panic, the impact is a denial of service with no known public exploit yet. The risk remains high because any user able to interact with the driver can bring the host down. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog, but the severity is still worrisome due to the catastrophic effect of a kernel panic.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

Upgrade the Linux kernel to a version where the wave5 driver patch has been applied.
If a kernel update is not immediately possible, disable autosuspend for the wave5 device by writing "0" to /sys/bus/pci/devices/<device>/power/autosuspend or by setting power/control to "on" via udev rules.
Configure a watchdog timer so the system automatically reboots after a panic, limiting downtime.
