CVE-2024-6759

The CVE-2024-6759 issue affects FreeBSD NFS client behavior: the kernel does not sanitize remotely provided filenames containing the path separator "/" when mounting a remote filesystem, allowing readdir(3) and related calls to return entries with extra path components. This creates a confused de...

FreeBSD -- NFS client accepts file names containing path separators

Problem Description: When mounting a remote filesystem using NFS, the kernel did not sanitize remotely provided filenames for the path separator character, "/". This allows readdir3 and related functions to return filesystem entries with names containing additional path components. Impact: The la...

CVE-2022-48827

CVE-2022-48827 (Linux kernel NFSD READ near OFFSET_MAX) : The vulnerability arises when the client-side NFS read request is aligned to a server rsize of 0x1000 due to a buffer alignment change. This can cause a loff_t overflow on the server when reading near the maximum file offset, leading the s...

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 : 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...
