| |
Hi All: net/wireless/chan.c: Inside function cfg80211_chandef_compatible(), variable "c1_pri40", " c2_pri40", "c1_pri80" and "c2_pri80" could be uninitialized if chandef_primary_freqs() fails. However, they are used later in the if statement to decide the control flow, which is potentially unsafe.
The patch is hard since we do not know the correct value to initialize them. -- Kind Regards,
