CVE-2022-50876 (GCVE-0-2022-50876)

Vulnerability from cvelistv5 – Published: 2025-12-30 12:23 – Updated: 2026-05-11 19:26

Title

usb: musb: Fix musb_gadget.c rxstate overflow bug

Summary

In the Linux kernel, the following vulnerability has been resolved: usb: musb: Fix musb_gadget.c rxstate overflow bug The usb function device call musb_gadget_queue() adds the passed request to musb_ep::req_list,If the (request->length > musb_ep->packet_sz) and (is_buffer_mapped(req) return false),the rxstate() will copy all data in fifo to request->buf which may cause request->buf out of bounds. Fix it by add the length check : fifocnt = min_t(unsigned, request->length - request->actual, fifocnt);

Severity

No CVSS data available.

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.
