CVE-2026-89696
In the Linux kernel, the following vulnerability has been resolved: nfsd: block non-SAVEFH ops after FOREIGN PUTFH to prevent NULL deref When CONFIGNFSDV42INTERSSC is enabled, nfsd4putfh can return success with fhdentry and fhexport both NULL if fhverify returns nfserrstale and putfh-noverify is...
CVE-2026-89697
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
A Denial of Service vulnerability in the Linux kernel's NFSD (Network File System Daemon) component. The nfsd4_decode_posixacl() function reads a client-supplied u32 entry count without capping it, passing it directly to an O(nĀ²) bubble sort (sort_pacl_range()). A remote attacker can send a craft...
CVE-2026-89695 nfsd: cap decoded POSIX ACL count to bound sort cost
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-2026-89693 nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()
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...
CVE-2026-89692 nfsd: clear CALLBACK_RUNNING on failed delegation recall queue
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-2026-89692
CVE-2026-89692 is a denial-of-service vulnerability in the Linux kernel's nfsd (NFS daemon). When a delegation recall queue attempt fails, the NFSD4_CALLBACK_RUNNING flag is left permanently set because the only code path that clears it (nfsd41_destroy_cb) is unreachable in that scenario. This ca...
CVE-2026-89693
CVE-2026-89693 affects the Linux kernel's NFS daemon (nfsd) . The vulnerability is in the nfsd4_create() function, where the return value of nfsd4_acl_to_attr() is stored in status but unconditionally overwritten by every branch of the switch(create->cr_type) block. As a result, ACL translatio...

In the Linux kernel, the following vulnerability has been resolved: nfsd: clear opcnt on compound arg release to prevent OOB read nfsd4releasecompoundargs resets args-ops to the inline iops8 array when the dynamically-allocated ops buffer is freed, but leaves args-opcnt at its original value whic...
CVE-2026-89691
CVE-2026-89691 is an out-of-bounds read vulnerability in the Linux kernel's nfsd (Network File System Daemon) component. The nfsd4_release_compoundargs() function resets the args->ops pointer to the inline iops[8] array when the dynamically allocated buffer is freed, but fails to zero args->...
