Title
wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init()
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: Fix null-ptr-deref in mt7915_mmio_wed_init()
devm_ioremap() returns NULL on error. Currently, mt7915_mmio_wed_init()
does not check for this case, which results in a NULL pointer
dereference.
Prevent null pointer dereference in mt7915_mmio_wed_init().

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.
