Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a deadlock issue involving NFSv4.1 state recovery. The deadlock occurs when
kthreadd attempts to reclaim memory by calling the nfs release folio() function, which is blocked due to the need for state recovery. The issue involves waiting on kthreadd while state recovery is in progress, preventing nfs release folio() from making progress. A potential resolution involves initiating a writeback of the folio without waiting for completion or triggering an asynchronous commit.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
