GHSA-M647-H22J-V38Q

Vulnerability from github – Published: 2024-03-01 00:30 – Updated: 2024-11-06 18:31

Details

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

crypto: sun8i-ss - Fix memory leak of object d when dma_iv fails to map

In the case where the dma_iv mapping fails, the return error path leaks the memory allocated to object d. Fix this by adding a new error return label and jumping to this to ensure d is free'd before the return.

Addresses-Coverity: ("Resource leak")

Severity

5.5 (Medium)

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
