In the Linux kernel, the following vulnerability has been resolved:
ASoC: SDCA: Add better pm_runtime error handling in func probe
Add a common error path in probe that balances the runtime PM reference.
A flaw was found in the Linux kernel's SoundWire Device Class Architecture (SDCA) audio subsystem. When an error occurs during device initialization, the driver fails to properly balance runtime power management references. This improper resource handling can lead to power management inconsistencies or a local denial of service (DoS).
Отчет
In typical Red Hat Enterprise Linux environments, this issue presents minimal operational risk because exploitation requires physical presence of specialized SoundWire Device Class Architecture (SDCA) audio hardware that encounters a failure during device initialization. Standard enterprise server deployments and cloud instances do not utilize these sound interfaces. The flaw only results in an unbalanced runtime power management reference count if a probe fails, preventing any privilege escalation or remote code execution.
