kernel: smb: client: validate the whole DACL before rewriting it in cifsacl
A flaw was found in the Linux kernel's Server Message Block SMB client, specifically within the cifsacl functionality. A malicious SMB server could provide a malformed Discretionary Access Control List DACL that claims to contain more Access Control Entries ACEs than are actually present. This...
The vulnerability of the _nfs4_discover_trunking() function in the fs/nfs/nfs4proc.c module, which is part of the NFS client support in Linux kernel, allows a attacker to cause a service failure.
The vulnerability of the nfs4discovertrunking function in the fs/nfs/nfs4proc.c module, which is part of the NFS client support in Linux kernel, involves exposing confidential information. Exploiting this vulnerability could allow an attacker to cause service failures...
CVE-2026-23189
CVE-2026-23189 concerns a NULL pointer dereference in ceph_mds_auth_match() within the CephFS kernel client. The patch reworks ceph_mdsmap_decode() and namespace_equals() so that ceph_mdsmap contains an extracted FS name (m_fs_name) and the code path uses this value for strict authorization check...
CVE-2026-23189 ceph: fix NULL pointer dereference in ceph_mds_auth_match()
In the Linux kernel, the following vulnerability has been resolved: ceph: fix NULL pointer dereference in cephmdsauthmatch The CephFS kernel client has regression starting from 6.18-rc1. We have issue in cephmdsauthmatch if fsname == NULL: const char fsname = mdsc-fsc-mountoptions-mdsnamespace;...
kernel: libceph: fix potential use-after-free in have_mon_and_osd_map()
A use-after-free vulnerability was found in the Ceph client session initialization in the Linux kernel. The havemonandosdmap function checks map epochs without holding the appropriate locks, racing with concurrent map updates that free the old map. This can result in dereferencing freed memory...
kernel: smb/client: fix memory leak in smb2_open_file()
A memory leak flaw was found in the Linux kernel's CIFS/SMB client. In the smb2openfile function, request buffers are not properly freed when performing direct I/O writes to a read-only SMB share. This causes slab cache objects to remain allocated, which can prevent the cifs module from unloading...
