UBUNTU-CVE-2021-47260

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix a potential NULL dereference in nfsgetclient None of the callers are expecting NULL returns from nfsgetclient so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the nfsdrename function incorrectly cleaning up paths...

The vulnerability of the Linux operating system’s Network File System kernel allows a hacker to cause a service failure.

The vulnerability of the Linux operating system’s Network File System kernel lies in the lack of protection against unauthorized data processing during the execution of the .GETDEVICEINFO and LAYOUTGET operations in UDP packets. Exploiting this vulnerability can allow an attacker to cause service...

The vulnerability of the nfs_direct_commit_schedule() function in the fs/nfs/direct.c module of the Linux kernel’s Network File System (NFS) allows a attacker to cause a service failure.

The vulnerability of the nfsdirectcommitschedule function in the fs/nfs/direct.c module of the Linux kernel’s Network File System NFS module is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to cause a service failure...
