Vulnerability from fkie_nvd - Published: 2024-10-21 12:15 - Updated: 2026-08-04 11:20

Severity

8.8 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw89: remove unused C2H event ID RTW89_MAC_C2H_FUNC_READ_WOW_CAM to prevent out-of-bounds reading The handler of firmware C2H event RTW89_MAC_C2H_FUNC_READ_WOW_CAM isn't implemented, but driver expects number of handlers is NUM_OF_RTW89_MAC_C2H_FUNC_WOW causing out-of-bounds access. Fix it by removing ID. Addresses-Coverity-ID: 1598775 ("Out-of-bounds read")

Consistent with kernel CNA practice for firmware-supplied-index OOB bugs in wireless drivers, this is Adjacent rather than Network.\nAC:L - The class and func fields are consumed verbatim from the C2H header with no validation whatsoever, so a single event with class=0x3/func=1 deterministically triggers the out-of-bounds fetch and indirect call \u2014 no race, no memory-layout grooming, and no timing window is involved.\nPR:N - The C2H dispatch path is gated only by RTW89_FLAG_RUNNING (interface up); there is no capability check, no authentication, and no requirement that WoWLAN was configured by a privileged process. The attacker needs no credentials on the target system.\nUI:N - No victim action is required \u2014 the event is processed asynchronously in the driver\u0027s interrupt/work path as soon as it arrives, independent of any user activity such as suspending the machine or configuring WoWLAN.\nS:U - The out-of-bounds read and the resulting indirect call both occur within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Reading past the one-element handler table and invoking the resulting pointer produces a type confusion with adjacent same-signature C2H handlers, which cast skb-\u003edata to fixed structs and memcpy fixed lengths without honoring len \u2014 leaking out-of-bounds heap contents into driver state, including WoWLAN key-material buffers (GTK/PTK/IGTK/IV). Combined with the leak of kernel .rodata contents through the branch target, this is a high confidentiality impact.\nI:H - The OOB slot is dereferenced as a function pointer and called, so an attacker-induced event transfers control to an address the kernel never intended to branch to \u2014 a control-flow-integrity violation and potential code-execution primitive \u2014 while the type-confused handler also writes unvalidated firmware-controlled data into driver key/state structures.\nA:H - Calling a garbage or mismatched function pointer from interrupt/atomic context reliably produces a kernel oops, CFI panic, or memory corruption crash, and the event can be re-delivered repeatedly."

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.
