Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A deadlock warning occurred in the Linux kernel when invoking nfs4 put stid following a failed dl recall queue operation. This issue arises from the interaction between nfsd break one deleg and generic delete lease, where the disassociation process becomes blocked when attempting to acquire flc lock. To resolve this, sc count in nfsd break one deleg is decremented directly, avoiding the deadlock condition.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
