In the Linux kernel, the following vulnerability has been resolved: ath9k: fix use-after-free in ath9khifusbrxcb Syzbot reported use-after-free Read in ath9khifusbrxcb() [0]. The problem was in incorrect htchandle->drvpriv initialization. Probable call trace which can trigger use-after-free: ath9khtcprobedevice() /* htchandle->drvpriv = priv; */ ath9khtcwaitfortarget() <--- Failed ieee80211freehw() <--- priv pointer is freed <IRQ> ... ath9khifusbrxcb() ath9khifusbrxstream() RXSTATINC() <--- htchandle->drvpriv access In order to not add fancy protection for drvpriv we can move htchandle->drvpriv initialization at the end of the ath9khtcprobe_device() and add helper macro to make all STAT macros NULL safe, since syzbot has reported related NULL deref in that macros [1]
