Linux Distros Unpatched Vulnerability : CVE-2026-89485

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - lockd: pin next file across nlminspectfile lock-drop nlmtraversefiles pins the current file with fcount++ across a mutexunlock for nlminspectfile, but nothing...

CVE-2026-89485

A flaw was found in the lockd component of the Linux kernel. This use-after-free vulnerability occurs in the nlmtraversefiles function when a file's memory is prematurely released while an iterator still holds a pointer to it. A remote attacker could potentially exploit this to cause system...

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...
