The vulnerability of the nfsd4_copy() function in the fs/nfsd/nfs4proc.c module, which is part of the NFS network file system support in Linux kernel, allows a hacker to cause a service failure.

The vulnerability of the nfsd4copy function in the fs/nfsd/nfs4proc.c module, which is part of the NFS network file system support in Linux kernels, stems from an improper handling of reference counts when resources are utilized. Exploiting this vulnerability could allow a attacker to cause servi...

CVE-2024-53073

CVE-2024-53073 is a Linux kernel issue in NFSD’s NFSv4 copy path. The root cause is that on error, the nfsd4_copy() error path does not decrement pending_async_copies, whereas cleanup_async_copy() already decrements nn->pending_async_copies; this mismatch could affect resource accounting. The ...

SUSE CVE-2024-50241

In the Linux kernel, the following vulnerability has been resolved: NFSD: Initialize struct nfsd4copy earlier Ensure the refcount and asynccopies fields are initialized early. cleanupasynccopy will reference these fields if an error occurs in nfsd4copy. If they are not correctly initialized, at t...
