Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the
gem poll controller() function, which disables interrupts and may cause the system to sleep. However, sleeping is not allowed in netpoll, as it has interrupts disabled completely. The gem poll controller() function does not poll completions and instead acts as if an interrupt has fired, scheduling NAPI and exiting. This behavior has been unnecessary for years since netpoll invokes NAPI directly. The vulnerability has been resolved by removing the .ndo poll controller to avoid deadlocks.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
