CVE-2022-49362 Details
Description
In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix potential use-after-free in nfsd_file_put() nfsd_file_put_noref() can free @nf, so don't dereference @nf immediately upon return from nfsd_file_put_noref().
A use-after-free vulnerability has been identified in the Linux kernel's Network File System (NFS) server component. The issue arises in the file handling functions, specifically 'nfsd_file_put()' and 'nfsd_file_put_noref()'. The latter function can free a reference to a file, creating a potential use-after-free scenario if the reference is accessed immediately after the free operation.
