kernel: NFSv4/pnfs: Fix a use-after-free bug in open

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pnfs: Fix a use-after-free bug in open If someone cancels the open RPC call, then we must not try to free either the open slot or the layoutget operation arguments, since they are likely still in use by the hung RPC call...

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...

kernel: NFSD: Finish converting the NFSv2 GETACL result encoder

A flaw was identified in the Linux kernel’s NFSD NFSv2 GETACL result encoder. During conversion to xdrstream, leftover code erroneously set the pagelen field of the send buffer. The XDR stream encoders are expected to manage buffer length automatically, and the incorrect manual setting can result...

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: NFSD: Protect against send buffer overflow in NFSv2 READ

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. 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-2009-3286

NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an OEXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the...

SUSE CVE-2009-3726

The nfs4proclock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service NULL pointer dereference and panic by sending a certain response containing incorrect file attributes, which trigger attempted use of an...

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...
