CVE-2026-23297

CVE-2026-23297 affects the Linux kernel’s NFS daemon (nfsd). The issue is a memory leak of struct cred caused by how nfsd_nl_threads_set_doit() passes current credentials to nfsd_svc() and later to _svc_xprt_create() without transferring ownership, leaving a refcount leak. SYZBOT identified a lea...

ROS-20260323-73-0006

A vulnerability in the initnfsd function in the fs/nfsd/nfsctl.c module of the Linux kernel's NFS network file system support is related to NULL pointer dereferencing. Exploitation of the vulnerability could allow an attacker to cause a denial of service...

The vulnerability of the `pnfs_mark_layout_stateid_invalid()` function in the `fs/nfs/pnfs.c` module, which is part of the NFS client support in Linux kernel, allows an attacker to compromise the confidentiality, integrity, and accessibility of protected information.

The vulnerability of the pnfsmarklayoutstateidinvalid function in the fs/nfs/pnfs.c module relates to errors during link counters updates in Linux kernel-based NFS client support. Exploiting this vulnerability can allow attackers to compromise the confidentiality, integrity, and accessibility of...
