CVE-2024-26629

CVE-2024-26629: Linux kernel nfsd: fix RELEASE_LOCKOWNER. Connected advisories document a patch correcting a test on so_count in nfsd4_release_lockowner(), which could transiently report locks held and cause NFS4 errors. The fix reverts to check_for_locks() (made to not sleep) and prevents false ...

CVE-2023-6660

When a program running on an affected system appends data to a file via an NFS client mount, the bug can cause the NFS client to fail to copy in the data to be written but proceed as though the copy operation had succeeded. This means that the data to be written is instead replaced with whatever...

CVE-2023-6660

The CVE-2023-6660 issue affects FreeBSD NFS client (13.2/14.0) where appending data to a file via an NFS mount may cause the client to copy in data incorrectly and continue as if written, resulting in data being replaced by prior mbufs contents. This can leak sensitive information from mbuf buffe...

FreeBSD Security Vulnerabilities

FreeBSD is a set of Unix-like operating systems from the FreeBSD Foundation. A security vulnerability exists in FreeBSD versions 13.2 and 14.0, which stems from an information disclosure vulnerability in the NFS client...

FreeBSD : FreeBSD -- NFS client data corruption and kernel memory disclosure (8eefff69-997f-11ee-8e38-002590c1f29c)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 8eefff69-997f-11ee-8e38-002590c1f29c advisory. - In FreeBSD 13.2 and 14.0, the NFS client was optimized to improve the performance of IOAPPEND writes,...

FreeBSD -- NFS client data corruption and kernel memory disclosure

Problem Description: In FreeBSD 13.2 and 14.0, the NFS client was optimized to improve the performance of IOAPPEND writes, that is, writes which add data to the end of a file and so extend its size. This uncovered an old bug in some routines which copy userspace data into the kernel. The bug also...

K80622270: Linux kernel vulnerability CVE-2020-10742

Security Advisory Description A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause a kernel panic. The highest threat from this...

K42355373: Linux NFS kernel vulnerablity CVE-2020-25212

Security Advisory Description A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452...

K72225092: Linux kernel vulnerability CVE-2015-8746

Security Advisory Description fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service NULL pointer dereference and panic via crafted network traffic...
