In the Linux kernel, the following vulnerability has been resolved:

dlm: validate length in dlm_search_rsb_tree

The len parameter in dlm_dump_rsb_name() is not validated and comes from network messages. When it exceeds DLM_RESNAME_MAXLEN, it can cause out-of-bounds write in dlm_search_rsb_tree().

Add length validation to prevent potential buffer overflow.
