FKIE_CVE-2026-72133
Vulnerability from fkie_nvd - Published: 2026-08-15 06:21 - Updated: 2026-08-17 06:18
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: uniphier: Fix completion initialization order before devm_request_irq()
The driver calls devm_request_irq() before initializing the completion
used by the interrupt handler. Because the interrupt may occur immediately
after devm_request_irq(), the handler may execute before init_completion().
This may result in calling complete() on an uninitialized completion,
causing undefined behavior. This has been observed with KASAN.
Fix this by initializing the completion before registering the IRQ.

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.
