CVE-2026-90163

In the Linux kernel, the following vulnerability has been resolved: smb/server: call ksmbd_proc_cleanup() on module init failure When a later initializer fails, the unwind chain releases resources created after procfs and then jumps directly to class_unregister(). Returning an error from module_init() leaves the proc tree and its per-CPU counters allocated.
