Publication date: 2026-03-25

Last updated on: 2026-04-24

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: wifi: rsi: Don't default to -EOPNOTSUPP in rsi_mac80211_config This triggers a WARN_ON in ieee80211_hw_conf_init and isn't the expected behavior from the driver - other drivers default to 0 too.

Executive Summary

This vulnerability is in the Linux kernel's wifi driver, specifically in the rsi driver. The issue is that the driver defaults to returning the error code -EOPNOTSUPP in the function rsi_mac80211_config, which triggers a warning (WARN_ON) in the ieee80211_hw_conf_init function. This behavior is unexpected because other wifi drivers default to returning 0 in this situation.

Impact Analysis

The vulnerability causes an unexpected warning in the Linux kernel's wifi driver during hardware configuration initialization. While the exact impact is not detailed, such warnings can lead to instability or improper handling of wifi hardware configuration, potentially affecting wireless connectivity or system reliability.
