Vulnerability from github – Published: 2024-05-01 15:30 – Updated: 2025-09-18 18:30

Details

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

clk: hisilicon: hi3559a: Fix an erroneous devm_kfree()

'p_clk' is an array allocated just before the for loop for all clk that need to be registered. It is incremented at each loop iteration.

If a clk_register() call fails, 'p_clk' may point to something different from what should be freed.

The best we can do, is to avoid this wrong release of memory.

Severity

5.5 (Medium)

Detection rules are retrieved from Rulezet.

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.
