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-2026-89681

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...

CVE-2026-89688

A flaw was found in the Linux kernel's nfsd component. During a seqidop replay retry, the system incorrectly handles reference counts for stateowners, leading to a reference count underflow and a use-after-free vulnerability. This issue could allow an attacker to potentially cause a denial of...

CVE-2026-89683

A flaw was found in the Linux kernel's nfsd NFS daemon. A remote attacker could exploit this vulnerability by sending a specially crafted NFSv3 filehandle targeting a V4ROOT export's file system identifier fsid. This action triggers a dentry reference leak, which can lead to resource exhaustion a...

CVE-2026-89473

A flaw was found in the Linux kernel's bq25890 power supply driver. The bq25890fwprobe function acquires a reference to a secondary charger but fails to release it on subsequent probe failures or driver detach. This reference leak can lead to resource exhaustion over time, potentially allowing a...

CVE-2026-80983

A flaw was found in the Linux kernel's implementation of the Server Message Block SMB over Remote Direct Memory Access RDMA protocol, specifically within the net/smc component. An error path in the smcswitchconns function, triggered during link failover events, can lead to a socket reference coun...

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-2026-89447

A flaw was found in the Linux kernel's iommufd subsystem. A local attacker could exploit a vulnerability where an object reference is leaked during the unmapping of internal accesses. This occurs because the iommufdaccessnotifyunmap function incorrectly locks an object before checking if the acce...

CVE-2026-54258

ZoneMinder is a free, open source closed-circuit television software application. Versions prior to 1.36.39, 1.38.4, and 1.39.11 allow an authenticated low-privileged user with coarse Events=View and/or Snapshots=View permissions to directly fetch media for events belonging to monitors they are n...

CVE-2026-89512

A flaw was found in the Linux kernel's remoteproc SCP component. This vulnerability involves a device reference leak, where the system fails to properly release a reference to a device during a driver data lookup. This occurs specifically before the driver has been fully bound. A local attacker...

CVE-2026-89544

A flaw was found in the Linux kernel's SUNRPC component. Multiple defects in the gssxdecoptionarray XDR option-array decoder's error handling can lead to a NULL dereference, a reference count leak, and a use-after-free vulnerability. An attacker could potentially exploit these issues by providing...

CVE-2026-89593

A flaw was found in the Linux kernel's huge page hugetlb subsystem. This vulnerability occurs when a huge page of memory is shared between a parent and a child process. If the parent process unmaps the huge page before the child, the system can incorrectly reduce the count of reserved huge pages...
