Vulnerability from github – Published: 2024-05-19 12:30 – Updated: 2025-09-23 18:30

Details

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

crypto: iaa - Fix async_disable descriptor leak

The disable_async paths of iaa_compress/decompress() don't free idxd descriptors in the async_disable case. Currently this only happens in the testcases where req->dst is set to null. Add a test to free them in those paths.

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.
