**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability has been resolved in the Linux kernel related to the sound/virtio module. The issue arises when the `virtsnd probe()` function triggers an error path, leading to a call to `virtsnd remove()`, which iterates over substreams and calls `cancel work sync()` on an uninitialized `elapsed period` work struct. This results in a warning being generated. The problem occurs when an error is encountered during the allocation of information or if `virtsnd ctl query info()` fails, causing the function to exit without initializing the `elapsed period` work struct. The proposed fix involves initializing the substreams structure immediately after allocation to prevent the cleanup of uninitialized data. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
