CVE-2022-50640 (GCVE-0-2022-50640)

Vulnerability from cvelistv5 – Published: 2025-12-09 00:00 – Updated: 2026-05-11 19:22

Title

mmc: core: Fix kernel panic when remove non-standard SDIO card

Summary

In the Linux kernel, the following vulnerability has been resolved: mmc: core: Fix kernel panic when remove non-standard SDIO card SDIO tuple is only allocated for standard SDIO card, especially it causes memory corruption issues when the non-standard SDIO card has removed, which is because the card device's reference counter does not increase for it at sdio_init_func(), but all SDIO card device reference counter gets decreased at sdio_release_func().

Severity

No CVSS data available.

Assigner

Linux mitre root

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.
