The leak can cause gradual kernel memory depletion, leading to service degradation, crashes, or a panic. This issue is classified as CWE\u2011401 and has a CVSS score of 5.5, indicating moderate impact. It manifests during typical SMB operations such as mounting a read\u2011only share, creating a file, unmounting, and removing the module.", "risk_and_exploitability": "The CVSS rating of 5.5 reflects moderate severity, while EPSS is less than 1\u202f% and the vulnerability is not in the CISA KEV catalog, suggesting low exploitation probability.
