CVE-2026-90163 PUBLISHED

smb/server: call ksmbd_proc_cleanup() on module init failure

Assigner: Linux
Reserved: 11.09.2026 Published: 17.09.2026 Updated: 17.09.2026

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.
