Title
tipc: fix the msg->req tlv len check in tipc_nl_compat_name_table_dump_header
Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: fix the msg->req tlv len check in tipc_nl_compat_name_table_dump_header
This is a follow-up for commit 974cb0e3e7c9 ("tipc: fix uninit-value
in tipc_nl_compat_name_table_dump") where it should have type casted
sizeof(..) to int to work when TLV_GET_DATA_LEN() returns a negative
value.
syzbot reported a call trace because of it:

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.
