Summary

[none]

Details

In the Linux kernel, the following vulnerability has been resolved:

cfg80211: call cfg80211stopap when switch from P2P_GO type

If the userspace tools switch from NL80211IFTYPEP2PGO to NL80211IFTYPEADHOC via sendmsg(NL80211CMDSETINTERFACE), it does not call the cleanup cfg80211stopap(), this leads to the initialization of in-use data. For example, this path re-init the sdata->assignedchanctxlist while it is still an element of assignedvifs list, and makes that linked list corrupt.
