In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: use work to update rate to avoid RCU warning
The ieee80211ops::starcupdate must be atomic, because ieee80211chanbwchange() holds rcuread lock while calling drvstarcupdate(), so create a work to do original things.
Voluntary context switch within RCU read-side critical section!
