Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue in the NFS implementation where an Oops may occur in the nfs d automount() function when mounting from an NFSv4 referral. This happens because path->dentry can become a negative dentry, leading to an attempt to derive the nfs server structure from the dentry itself.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
