CVE-2022-50302

CVE-2022-50302 concerns the Linux kernel mutual-exclusion lock handling in lockd and vfs_lock_file. The approved description states that vfs_lock_file() expects a fully initialized struct file_lock, and that re-exported NFSv3 could OOPS if fl_file is NULL after unlocking, indicating a potential l...

CVE-2022-50302 lockd: set other missing fields when unlocking files

In the Linux kernel, the following vulnerability has been resolved: lockd: set other missing fields when unlocking files vfslockfile expects the struct filelock to be fully initialised by the caller. Re-exported NFSv3 has been seen to Oops if the flfile field is NULL...

SUSE CVE-2022-49321

In the Linux kernel, the following vulnerability has been resolved: xprtrdma: treat all calls not a bcall when bcserv is NULL When a rdma server returns a fault format reply, nfs v3 client may treats it as a bcall when bc service is not exist. The debug message at rpcrdmabcreceivecall are,...

CVE-2024-56740 nfs/localio: must clear res.replen in nfs_local_read_done

In the Linux kernel, the following vulnerability has been resolved: nfs/localio: must clear res.replen in nfslocalreaddone Otherwise memory corruption can occur due to NFSv3 LOCALIO reads leaving garbage in res.replen: - nfs3readdone copies that into server-readhdrsize; from there nfs3procreadset...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to memory corruption that can occur due to NFSv3 LOCALIO reads leaving garbage in res.replen. This happens when nfs3 read done copies the value into server-read...

kernel: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes

A vulnerability was found in the Linux kernel's NFSD, specifically in the handling of large file sizes during NFSv3 SETATTR and CREATE operations. The iasize field, being a signed 64-bit type, can lead to unexpected behavior when clients send size values larger than the maximum allowed. This...

SUSE CVE-2022-48829

In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes iattr::iasize is a lofft, so these NFSv3 procedures must be careful to deal with incoming client size values that are larger than s64max without corrupting the value...

kernel: NFSD: Protect against send buffer overflow in NFSv3 READDIR

A buffer management flaw was found in the Linux kernel's NFS server implementation in the NFSv3 READDIR operation handling. A remote client can trigger this issue by crafting an RPC call with an oversized RPC record header, which forces the server to shrink its response buffer allocation. This...

kernel: Linux kernel lockd: Denial of Service via uninitialized file lock field in NFSv3

A flaw was found in the Linux kernel's lockd component, which handles file locking. A local user could exploit this vulnerability by interacting with re-exported NFSv3 Network File System version 3 shares. This could cause the kernel to crash, leading to a Denial of Service DoS for the system...

SUSE CVE-2017-7895

The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and...
