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

The Linux kernel contains an issue within the NFS implementation. Specifically, when the TLS security policy is set to RPC XPRTSEC TLS X509, the
nfs match client() function does not properly validate the cert serial and privkey serial fields. These fields are crucial for defining the client's identity as presented to the server, and a mismatch can lead to security concerns.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
