Description OSIDB Bzimport 2026-03-25 11:06:42 UTC 
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.
