CVE-2026-89532 svcrdma: Fix pcl_for_each_segment for empty chunks

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Fix pclforeachsegment for empty chunks When a parsed chunk list contains a chunk whose chsegcount is zero, pclforeachsegment computes its inclusive upper bound as &chunk-chsegmentschsegcount - 1. chsegcount is u32, so th...

CVE-2026-89530 svcrdma: Reject inline replies that overflow the pull-up buffer

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Reject inline replies that overflow the pull-up buffer An RPC-over-RDMA client can request a reply, such as an NFS READ payload, without providing a Write list or a Reply chunk to carry it. When such a reply needs more...

CVE-2026-89485 lockd: pin next file across nlm_inspect_file lock-drop

In the Linux kernel, the following vulnerability has been resolved: lockd: pin next file across nlminspectfile lock-drop nlmtraversefiles pins the current file with fcount++ across a mutexunlock for nlminspectfile, but nothing pins the saved next pointer. A concurrent nlmreleasefile can kfree the...

CVE-2026-89485

CVE-2026-89485 is a use-after-free vulnerability in the Linux kernel's lockd (NLM) subsystem. In nlm_traverse_files(), the current file is pinned across a mutex_unlock window, but the saved next pointer is not. A concurrent nlm_release_file() can free that next file, causing the iterator to deref...

CVE-2026-89484 lockd: fix NULL dereference on lockowner allocation failure

In the Linux kernel, the following vulnerability has been resolved: lockd: fix NULL dereference on lockowner allocation failure nlmclntlocksinitprivate installs NLM file lock operations even when nlmclntfindlockowner fails to allocate a lockowner. nlmclntproc then returns -ENOMEM, but the VFS sti...

CVE-2026-89484

CVE-2026-89484 is a NULL pointer dereference in the Linux kernel's lockd (Network Lock Manager) subsystem. The bug occurs when nlmclnt_find_lockowner() fails to allocate a lockowner, yet nlmclnt_locks_init_private() still installs NLM file lock operations. When the VFS subsequently tears down the...
