- 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.
