Astra Linux – Vulnerability in Linux

The fs/nfs/nfs4client.c file in the Linux kernel before version 5.13.4 has an incorrect connection-setup ordering. This allows operators of remote NFSv4 servers to cause a denial of service termination of services, by arranging for those servers to become unreachable during trunking detection...

Astra Linux – Vulnerability in Linux

A memory-bound write flaw 1 or 2 bytes of memory was identified in the Linux kernel’s NFS subsystem, related to the way users use mirroring replication of files via NFS. A user with access to the NFS mount could potentially exploit this flaw to crash the system or escalate privileges on the syste...

In the Linux kernel, the following vulnerability has been resolved: NFS: Do not corrupt the value of pgbyteswritten in nfsdorecoalesce The value of mirror-pgbyteswritten should only be updated after a successful attempt to flush out the requests on the list...

Astra Linux – Vulnerability in Linux, Linux 5.10

A issue was discovered in fs/nfs/dir.c in the Linux kernel before version 5.16.5. If an application sets the ODIRECTORY flag and attempts to open a regular file, nfsatomicopen performs a regular lookup. If a regular file is found, ENOTDIR should be returned; however, the server instead returns...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: lockd: Other missing fields are set when unlocking files. The vfslockfile function expects that the struct filelock structure is fully initialized by the caller. If the flfile field is NULL after re-exporting NFSv3, an OOP err...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: NFSv4.2: fixed the NFSv4.2 kernel bug at mm/usercopy.c:102 Calling listxattr with a buffer size of 0 returns the actual size of the buffer required for a subsequent call. When size 0, nfs4listxattr does not return an error becaus...

Astra Linux – Vulnerability found in Linux 5.15, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: NFSD: Avoid calling OPDESC with ops-opnum == OPILLEGAL OPDESC simply indexes into nfsd4ops based on the operation number, without any range checking of that value. It assumes that callers will be careful enough to avoid calling...
