CVE-2026-89711

A flaw was found in the Linux kernel's Network File System Daemon NFSD. An invalid assumption in the nfsdmodecheck function regarding directory lookup capabilities during NFS reexport could lead to a null pointer dereference. A remote attacker could exploit this by performing a LOOKUP operation o...

CVE-2026-89672

A flaw was found in the Linux kernel's Network File System NFS server daemon nfsd. When processing NFSACL version 2 SETACL requests, the system could unintentionally remove a directory's default Access Control List ACL or both access and default ACLs. This occurs because the setposixacl function ...

CVE-2026-89702

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When processing NFSv2/v3-over-UDP requests, the nfsdfhverify and nfsdfhverifyerr tracepoints incorrectly size a memory buffer. This can lead to an out-of-bounds write, potentially allowing a remote attacker to cause a denial ...

CVE-2026-89715

A flaw was found in the Linux kernel's NFS/localio component. A race condition during file handling can lead to a reference leak, where system resources are not properly released. This continuous accumulation of unreleased references can exhaust available resources, preventing network namespace...

CVE-2026-89696

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A remote client can exploit this by sending a specially crafted NFS COMPOUND request. This request, when processed, can lead to a NULL pointer dereference in the nfsd kthread, causing the system to crash and resulting in ...

CVE-2026-89677

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When creating files, the dentrycreate function could return an unexpected directory entry dentry. This could lead to a previously stored dentry being prematurely freed and then used again, potentially causing memory corruptio...

CVE-2026-89673

A flaw was found in the Linux kernel's NFS daemon nfsd. A remote attacker could exploit an error in the XDR External Data Representation padding calculation within the ffencodegetdeviceinfo function. This mismatch between reserved and actual data size leads to the leakage of stale reply-page...

CVE-2026-89670

A flaw was found in the Linux kernel's Network File System Daemon nfsd component. A race condition exists in the nfsdopenlocalfh function where an nfsdfile object can be freed and its memory recycled while another process attempts to access it. This can lead to a use-after-free vulnerability,...

CVE-2026-89698

A flaw was found in the Linux kernel's nfsd component. When an IPv6 NFS client is connected, the nfsdgenlrpcstatuscomposemsg function incorrectly handles address fields, leading to an out-of-bounds read. A local unprivileged attacker can exploit this vulnerability to disclose sensitive kernel...

CVE-2026-89546

A flaw was found in the Linux kernel's SUNRPC Sun Remote Procedure Call Network File System NFS callback service. A race condition during the service teardown can lead to system resources not being properly released, causing a resource leak. This issue could also result in a use-after-free...

CVE-2026-89701

A flaw was found in the Linux kernel's Network File System Daemon nfsd. The TIMEDELEGACCESS and TIMEDELEGMODIFY decode paths do not properly validate the nanosecond nseconds value in timestamps. This allows a remote attacker to provide a malformed timestamp, which can then be written to disk,...

CVE-2026-89697

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When setting file attributes using nfsdprocsetattr, a specific code path BOTHTIMESET branch prematurely verifies file handles. This bypasses a critical write verification step fhwantwrite, allowing file attribute changes to...

CVE-2026-89537

A flaw was found in the Linux kernel's SUNRPC implementation, specifically within the gsskrb5verifymicv2 function. A remote malicious Network File System NFS server could provide a specially crafted, short Kerberos Message Integrity Code MIC token. This could lead to the kernel reading past an...

CVE-2026-89652

A flaw was found in the Linux kernel's Ceph file system. A malicious or compromised Ceph Metadata Server MDS can send a specially crafted LOOKUPNAME reply that causes a buffer overflow when copying dentry names during an NFS export operation. This out-of-bounds write can lead to memory corruption...
