The vulnerability of the nfs4_free_ol_stateid() function in the fs/nfsd/nfs4state.c module, which supports the Network File System in Linux kernels, allows a attacker to cause a service failure.

The vulnerability of the nfs4freeolstateid function in the fs/nfsd/nfs4state.c module, which is part of the network file system support in Linux kernels, relates to operations involving resources after their expiration. Exploiting this vulnerability could allow a remote attacker to cause service...

The vulnerability of the nfsd4_encode_fattr4() function in the fs/nfsd/nfs4xdr.c module, which is part of the Linux kernel’s Network File System support, allows a hacker to cause a service failure.

The vulnerability of the nfsd4encodefattr4 function in the fs/nfsd/nfs4xdr.c module, which is part of the Linux kernel’s Network File System support, is related to incorrect input validation. Exploiting this vulnerability could allow an attacker to cause service failures...

The vulnerability of the nfsd_net_init() function in the fs/nfsd/nfsctl.c module, which supports the NFS network file system in Linux kernels, allows a attacker to cause a service failure.

The vulnerability of the nfsdnetinit function in the fs/nfsd/nfsctl.c module, which supports the NFS network file system in Linux kernels, is related to the lack of checking for the return value. Exploiting this vulnerability could allow an attacker to cause a service failure...

Kernel: use-after-free in nfsd4_ssc_setup_dul in fs/nfsd/nfs4proc.c

A use-after-free flaw was found in nfsd4sscsetupdul in fs/nfsd/nfs4proc.c in the NFS filesystem in the Linux Kernel. This issue could allow a local attacker to crash the system or it may lead to a kernel information leak problem...

CVE-2021-38202: Out-of-bounds Read

fs/nfsd/trace.h in the Linux kernel before 5.13.4 might allow remote attackers to cause a denial of service out-of-bounds read in strlen by sending NFS traffic when the trace event framework is being used for nfsd...

The vulnerability in the `fs/nfsd/vfs.c` component of the Linux operating system allows a hacker to gain unauthorized access to protected information.

The vulnerability of the fs/nfsd/vfs.c component in the Linux operating system is related to insufficient checking of permission assignment for critical resources. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information...

Updated kernel packages fix security vulnerabilities

This kernel update is based on upstream 5.10.12 and fixes at least the following security issues: fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPL...

CVE-2021-3178: Improper Limitation of a Pathname to a Restricted Directory

fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this attac...

CVE-2020-24394: Incorrect Permission Assignment for Critical Resource

In the Linux kernel before 5.7.8, fs/nfsd/vfs.c in the NFS server can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered...

CVE-2017-7895: Improper Restriction of Operations within the Bounds of a Memory Buffer

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...

CVE-2017-7645: Improper Input Validation

The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service system crash via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c...
