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...
