CVE-2026-90165

CVE-2026-90165 is an invalid pointer dereference in the Linux kernel's ksmbd (SMB server) subsystem. The root cause is in ksmbd_launch_ksmbd_durable_scavenger(): when kthread_run() fails, server_conf.dh_task is set to an ERR_PTR() while durable_scavenger_running remains true . A subsequent call t...

CVE-2026-90164

CVE-2026-90164 affects the ksmbd (SMB server) subsystem in the Linux kernel . The root cause is that ksmbd_proc_init() returns void after a procfs or percpu_counter allocation failure, causing ksmbd_server_init() to continue with NULL per-CPU counters. On SMP systems , this leads to a NULL pointe...

CVE-2026-90162

In the Linux kernel, the following vulnerability has been resolved: ksmbd: defer publishing granted locks to prevent UAF/double-free race In smb2lock, mid-batch granted locks are published to connection-wide conn-locklist and file-wide fp-locklist lists immediately upon vfslockfile success, while...

CVE-2026-90163

This CVE affects the Linux kernel ksmbd (SMB server) module. When a later initializer during ksmbd module initialization fails, the unwind path releases resources created after the procfs setup but jumps directly to class_unregister() , leaving the proc tree and its per-CPU counters allocated wit...
