CVE-2026-89680

A flaw was found in the Linux kernel's nfsd component. This vulnerability occurs when an inter-server COPY operation fails during its setup phase, leading to improper resource cleanup. Consequently, each failed operation results in a memory leak, consuming system resources. A remote attacker coul...

CVE-2026-89704

A flaw was found in the Linux kernel's nfsd component. The nfsdcopyfilerange function incorrectly samples the writeback error cursor after the copy loop. This allows a concurrent write operation to advance the error cursor prematurely. As a result, the system may report that data has been...

CVE-2026-89676

A flaw was found in the Linux kernel's Network File System Daemon nfsd component. When performing an asynchronous async copy operation, a programming error causes a stale identifier IDR entry to point to memory that has already been reused. This can lead to memory corruption, where the system...

CVE-2026-89675

A flaw was found in the Linux kernel's nfsd component. A race condition exists during asynchronous copy cancellation and shutdown operations, which can lead to a Use-After-Free UAF vulnerability. This allows an async copy object to be freed or used after being freed, potentially causing memory...

CVE-2026-89685

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A clock domain mismatch in the clientsstillreclaiming function allows a remote attacker to indefinitely hold the server in a grace period. By sending specific CLAIMPREVIOUS OPEN requests, an attacker can block all...

CVE-2026-89712

A flaw was found in the Linux kernel's Network File System Daemon NFSD component. A race condition exists where, during the processing of unmounted source-server mounts, a thread may temporarily release a lock. During this window, another NFS Remote Procedure Call RPC thread can free memory that...

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-2026-89663

A flaw was found in the Linux kernel's Network File System Daemon nfsd. This vulnerability arises from improper handling of "copy-notify stateids" during their revocation. When a stateid's reference is dropped without unlinking it, the memory can be freed while still in use by a reader, leading t...

CVE-2026-89709

A flaw was found in the Linux kernel's lockd and nfsd components. An unguarded dereference of nlmsvcops after the nfsd module is removed can lead to a NULL pointer dereference or a use-after-free condition. This vulnerability could allow a local attacker to cause a denial of service...

CVE-2026-89678

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd component. The nfsddirectwrite function, responsible for handling direct writes, incorrectly detects partial writes. This issue occurs because the logic for detecting short writes compares the actual bytes written against ...

CVE-2026-89699

A flaw was found in the Linux kernel's Network File System Daemon nfsd when handling NFSv4 CREATE operations. A remote attacker can exploit this by sending a crafted request with an oversized symbolic link symlink target length. This unbounded length can force the kernel to allocate a large amoun...

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-2026-89658

A flaw was found in the Linux kernel's Network File System Daemon NFSD. During NFSv4.0 revoked-state cleanup, a race condition can occur where a client's state identifier stateid reference does not properly prevent the client from being prematurely freed while still in use. This use-after-free...

CVE-2026-89669

A flaw was found in the nfsd component of the Linux kernel. A use-after-free vulnerability exists due to improper initialization of the copy-notify state ID before its publication. A remote attacker could exploit this by sending a crafted OFFLOADCANCEL operation, leading to a race condition that...

CVE-2026-89659

A flaw was found in the Linux kernel's Network File System Daemon NFSD. This use-after-free vulnerability occurs during the delegation revoke process. When an expired delegation is unhashed, a timing window exists where the client can be prematurely freed before the revocation is complete. This c...

CVE-2026-89687

A flaw was found in the Linux kernel's Network File System Daemon nfsd. The nfsdfiledoacquire function might attempt to use a file that has not been fully opened, as the -atomicopen operation could return success prematurely. While this scenario is considered highly improbable, it could lead to...

CVE-2026-89684

A flaw was found in the Linux kernel's nfsd component. A remote attacker, by sending a specially crafted OFFLOADCANCEL request, could exploit a race condition during the initialization of copy state notifications. This could lead to a denial of service DoS by causing the server to crash...

CVE-2026-89690

A flaw was found in the nfsd component of the Linux kernel. This vulnerability, a use-after-free, occurs when a specific memory buffer is prematurely released while another process is still trying to access it. This timing issue can lead to memory corruption. This could result in a system crash...

CVE-2026-89679

A flaw was found in the Linux kernel's nfsd component. A remote attacker can exploit this by sending a specially crafted SETATTR request that includes specific delegation timestamp attributes and a special NFSv4 state ID. This triggers a null dereference, leading to a kernel crash and a Denial of...

CVE-2026-89660

A flaw was found in the Linux kernel's Network File System Daemon NFSD. This vulnerability, a use-after-free, occurs during the revocation of client administrative states. A race condition can allow a client's memory to be freed prematurely while still being referenced, potentially leading to...
