Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved, related to the unmount process of cached directory instances. The issue occurs when the unmount process races with various cached directory operations, resulting in dentries not being dropped and causing kernel bugs. This happens when a cfid is being cleaned up and has been removed from the cfids->entries list, including scenarios such as receiving a lease break from the server, server reconnection, or the laundromat thread expiring an old cfid. The solution involves dropping the dentry in queued work done in a newly-added workqueue and flushing that workqueue after dropping all the dentries of which it's aware.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
