Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') due to a race condition between the initialization of the workqueue and the registration of the network device in the probe and remove processes. An attacker can cause system instability or potentially trigger a denial of service by exploiting the timing window where the network device may queue work on a NULL workqueue.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
