Vulnerability from github – Published: 2026-04-03 18:31 – Updated: 2026-04-23 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

spi: amlogic-spisg: Fix memory leak in aml_spisg_probe()

In aml_spisg_probe(), ctlr is allocated by spi_alloc_target()/spi_alloc_host(), but fails to call spi_controller_put() in several error paths. This leads to a memory leak whenever the driver fails to probe after the initial allocation.

Convert to use devm_spi_alloc_host()/devm_spi_alloc_target() to fix the memory leak.

Severity

5.5 (Medium)

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.
