CVE-2022-49731 (GCVE-0-2022-49731)

Vulnerability from cvelistv5 – Published: 2025-02-26 02:24 – Updated: 2026-05-11 19:05

Title

ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo()

Summary

In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo() In an unlikely (and probably wrong?) case that the 'ppi' parameter of ata_host_alloc_pinfo() points to an array starting with a NULL pointer, there's going to be a kernel oops as the 'pi' local variable won't get reassigned from the initial value of NULL. Initialize 'pi' instead to '&ata_dummy_port_info' to fix the possible kernel oops for good... Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool.

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.
