Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to possible deadlocks in the core system-wide PM code of the Linux kernel. In low-memory situations, the system-wide resume core code deadlocks because
async schedule dev() executes its argument function synchronously if it cannot allocate memory, and this function attempts to acquire a mutex that is already held. Executing the argument function synchronously from within dpm async fn() may also be problematic for ordering reasons. The problem is addressed by changing the code to use async schedule dev nocall() for scheduling the asynchronous execution of device suspend and resume functions and to directly run them synchronously if async schedule dev nocall() returns false.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
