CVE-2026-90163

Estado: RecibidaSin puntuar—

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.
