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-2026-89705

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. This vulnerability occurs due to a synchronization issue where a status counter rqstatuscounter is not correctly reset on all exit paths within the nfsddispatch function. This can lead to a race condition where a lockles...

CVE-2026-89667

A flaw was found in the Linux kernel's Network File System Daemon nfsd file caching mechanism. A race condition can occur during concurrent shutdown operations and file disposal, where a file might be unhashed and moved to a dispose list, but the shutdown process misses it. This can lead to a...

CVE-2026-89692

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. This vulnerability occurs when a delegation recall operation fails, leaving a critical internal flag uncleared. This prevents subsequent attempts to break the same delegation, leading to a denial of service where file...

CVE-2026-89713

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A remote attacker, by sending a crafted file attribute modification request SETATTR while a file is being concurrently appended, could exploit a time-of-check to time-of-use TOCTOU vulnerability. This could lead to the...

CVE-2026-89689

A flaw was found in the Linux kernel's Network File System NFS daemon, nfsd. A remote attacker could exploit a use-after-free vulnerability in the nfsd4sequence function. This occurs when the system attempts to reduce the number of active session slots while a client is still using one of the slo...

CVE-2026-89665

A flaw was found in the Linux kernel's nfsd component. A remote attacker could exploit this vulnerability by sending a specially crafted NFSv2 SETATTR or CREATE request with an out-of-range 'useconds' value. This could lead to incorrect timestamps being written to the filesystem, resulting in dat...

CVE-2026-89662

A flaw was found in the Linux kernel's Network File System Daemon NFSD. During client teardown, a race condition can occur where a lock owner is freed while still being referenced, leading to a use-after-free vulnerability. This can result in a NULL dereference, potentially causing a system crash...

CVE-2026-89703

A flaw was found in the nfsd component of the Linux kernel. The nfsd4droprevokedstid function, which handles admin-revoked delegations, fails to correctly set a status flag before releasing a lock. This oversight can lead to a use-after-free condition when a freed delegation is incorrectly added ...

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-2026-89708

A flaw was found in the Linux kernel's NFS daemon nfsd. During the teardown of an NFSv4 session, a race condition can occur where the session's memory is freed while an active callback task still holds a reference to it. This can lead to a use-after-free vulnerability, potentially causing system...

CVE-2026-89700

A flaw was found in the Linux kernel's nfsd component. A local user with CAPNETADMIN capabilities can exploit this by sending a specially crafted network attribute with an incorrect address family length. This can lead to an out-of-bounds read, potentially disclosing sensitive information or...

CVE-2026-89707

A flaw was found in the Linux kernel's nfsd component. An authenticated Network File System NFS client can exploit this vulnerability by triggering a failed cross-mount operation through nfsdlookupdentry or the NFSv4 READDIR encode path. This leads to a reference count leak, which inflates mntcou...

CVE-2026-89549

A flaw was found in the sunrpc component of the Linux kernel. When the nfsd service runs with fewer threads than available pools, a transport can be routed to a pool with no active threads. This prevents the connection from being processed, causing it to hang indefinitely. This can lead to a Deni...

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-2026-89681

A flaw was found in the Linux kernel's nfsd component. A race condition in the layout fence worker can cause a double-reference to a layout stateid. This occurs because the workqueue core clears a pending flag prematurely, allowing a new worker to be scheduled while another is still active. The...
