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

Description The issue concerns the Linux kernel's handling of NFSv4.2, specifically with the nfs42 ssc open function. A problem arises when a destination server performs a COPY operation and accepts a filehandle that is not a regular filehandle. Additionally, there is an issue with alloc file pseudo() failing to decrement a reference on a newly created inode, leading to a leak.

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