FKIE_CVE-2021-47260

Vulnerability from fkie_nvd - Published: 2024-05-21 15:15 - Updated: 2024-12-24 16:35
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: NFS: Fix a potential NULL dereference in nfs_get_client() None of the callers are expecting NULL returns from nfs_get_client() so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so hopefully no one is affected.
