Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.2.6-1.1 Description An issue exists in the nfsd proc setattr function where the BOTH TIME SET branch triggers an early call to fh verify. This sequence allows setattr prepare to inspect the dentry but causes nf...

In the Linux kernel, the following vulnerability has been resolved: nfsd: reject out-of-range useconds in NFSv2 SETATTR/CREATE The NFSv2 sattr decoder converts the wire useconds to nanoseconds in svcxdr decode sattr: iap-ia atime.tv nsec = tmp2 NSEC PER USEC; tmp2 is a u32 and NSEC PER USEC is...

CVE-2026-89709: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: lockd, nfsd: RCU-protect nlmsvcops dispatch nlmsvcops is published by nfsdlockdinit and cleared by nfsdlockdshutdown with plain stores, while lockd dereferences it unguarded from dispatch sites in fs/lockd/svcsubs.c. The pointer...

CVE-2026-89697: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: add fhwantwrite for early-verified SETATTR in nfsdprocsetattr The BOTHTIMESET branch calls fhverify early so setattrprepare can inspect the dentry. This causes nfsdsetattr to skip fhwantwrite, so notifychange runs without a...

CVE-2026-89695: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: cap decoded POSIX ACL count to bound sort cost nfsd4decodeposixacl reads a u32 entry count off the wire and passes it straight to posixaclalloc and sortpaclrange. The latter is an On^2 bubble sort, so a client-chosen count...

CVE-2026-89692: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: clear CALLBACKRUNNING on failed delegation recall queue nfsdbreakonedeleg sets NFSD4CALLBACKRUNNING via testandsetbit at entry to serialize recall work, then calls nfsd4runcb to queue the recall. When the queue attempt fail...

CVE-2026-89668: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: move nfsddebugfsinit after nfsd4initslabs in initnfsd nfsddebugfsinit runs before nfsd4initslabs in initnfsd. If the slab allocation fails, the bare "return retval" bypasses nfsddebugfsexit, leaving orphan debugfs files wit...

CVE-2026-89665: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: reject out-of-range useconds in NFSv2 SETATTR/CREATE The NFSv2 sattr decoder converts the wire useconds to nanoseconds in svcxdrdecodesattr: iap-iaatime.tvnsec = tmp2 NSECPERUSEC; tmp2 is a u32 and NSECPERUSEC is 1000, so t...

In the Linux kernel, the following vulnerability has been resolved: nfsd: check client ownership when cancelling a copy-notify stateid On the OFFLOAD CANCEL path clp != NULL, manage cpntf state freed the target cpntf state without checking ownership. The lookup key st-si opaque.so id is allocated...

PT-2026-96439

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix nfsd file leak on inter-server COPY setup failure When nfsd4 setup inter ssc fails, nfsd4 copy returns nfserr offload denied directly, bypassing the out: label where release copy files would drop the nf dst reference...

CVE-2026-89678: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix partial-write detection in nfsddirectwrite nfsddirectwrite walks a list of write segments and, after each vfsiocbiterwrite, tries to detect a short write so the loop can stop before placing the next segment at a wrong...

CVE-2026-89693: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: check nfsd4acltoattr return value in nfsd4create nfsd4create stores the return value of nfsd4acltoattr in status, but the switchcreate-crtype block unconditionally overwrites it in every branch. ACL translation errors are...

In the Linux kernel, the following vulnerability has been resolved: nfsd: gate nfs2 setacl by argp-mask The NFSACL v2 SETACL path shares the decoder convention used by its v3 sibling: nfsaclsvc decode setaclargs fills in argp-acl access only when NFS ACL is set in the request mask and argp-acl...

CVE-2026-89664: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: nfsd: release OPEN-decoded posix ACLs via oprelease nfsd4decodecreatehow4 calls nfsd4decodefattr4, which allocates refcounted struct posixacl objects via posixaclalloc and stores them in open-oppacl and open-opdpacl. These pointe...
