Short explanation
A flaw in the clevis PKCS#11 pin causes the token PIN to be passed as a command-line argument. This exposes sensitive information to local users through process listing or the /proc filesystem.
The visibility of sensitive PKCS#11 token PIN values to local users can lead to confidentiality breaches and unauthorized access risks.
What should be done?
- Follow vendor advisories
- Account for patch status uncertainty
