Title
calipso: fix memory leak in netlbl_calipso_add_pass()
Summary
In the Linux kernel, the following vulnerability has been resolved:
calipso: fix memory leak in netlbl_calipso_add_pass()
If IPv6 support is disabled at boot (ipv6.disable=1),
the calipso_init() -> netlbl_calipso_ops_register() function isn't called,
and the netlbl_calipso_ops_get() function always returns NULL.
In this case, the netlbl_calipso_add_pass() function allocates memory
for the doi_def variable but doesn't free it with the calipso_doi_free().
BUG: memory leak
unreferenced object 0xffff888011d68180 (size 64):
comm "syz-executor.1", pid 10746, jiffies 4295410986 (age 17.928s)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
