Title
ipv4: icmp: validate reply type before using icmp_pointers
Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv4: icmp: validate reply type before using icmp_pointers
Extended echo replies use ICMP_EXT_ECHOREPLY as the outbound reply type.
That value is outside the range covered by icmp_pointers[], which only
describes the traditional ICMP types up to NR_ICMP_TYPES.
Avoid consulting icmp_pointers[] for reply types outside that range, and
use array_index_nospec() for the remaining in-range lookup. Normal ICMP
replies keep their existing behavior unchanged.

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.
