Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: NFSD: Prevention of potential integer overflows If the tag length is greater than or equal to U32MAX – 3, the addition of “length + 4” can lead to an integer overflow. This issue can be addressed by breaking down the decoding...

CVE-2025-0373

On 64-bit systems, the implementation of VOPVPTOFH in the cd9660, tarfs and ext2fs filesystems overflows the destination FID buffer by 4 bytes, a stack buffer overflow. A NFS server that exports a cd9660, tarfs, or ext2fs file system can be made to panic by mounting and accessing the export with ...

CVE-2025-0373 Buffer overflow in some filesystems via NFS

On 64-bit systems, the implementation of VOPVPTOFH in the cd9660, tarfs and ext2fs filesystems overflows the destination FID buffer by 4 bytes, a stack buffer overflow. A NFS server that exports a cd9660, tarfs, or ext2fs file system can be made to panic by mounting and accessing the export with ...

The vulnerability of the revoke_delegation() function in the fs/nfsd/nfs4state.c module of the Linux kernel-based Network File System (NFS) server allows a perpetrator to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the revokedelegation function in the fs/nfsd/nfs4state.c module of the Linux file system kernel relates to the reutilization of previously released memory due to competitive access to resources race condition. Exploiting this vulnerability could allow an attacker to compromis...
