**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A deadlock issue has been identified in the Linux kernel, specifically between the `pci dev lock()` function and the `sriov numvfs store()` path. The `sriov numvfs store()` path acquires the device lock before the config space access lock, while `pci dev lock()` previously acquired the config space access lock before the device lock. This could lead to a deadlock if the operations occur in a specific sequence. The issue has been resolved by reversing the order in `pci dev lock()` to acquire the device lock before the config space access lock. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
