"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: mvm: fix P2P-Device binding handling\n\nOur binding handling for P2P-Device can run into the following\nscenario, as observed by our testing:\n\n - a station interface is connected on some channel\n - the P2P-Device does a remain-on-channel (ROC) on that channel\n - the ROC ends, and the P2P-Device is removed from the binding,\n but the phy_ctxt pointer is left around as a PHY cache so we\n don't need to recalibrate to the channel again and again in\n case it's not shared\n - a binding update by the station interface, even a removal,\n will re-add the P2P-Device to the binding\n - the P2P-Device is removed, which removes the PHY context, but\n it's still in the binding so the firmware crashes\n\nSince the P2P device is removed from the binding and only re-\nadded by unrelated code, but we want to keep the phy_ctxt around\nas a cache for future ROC usage, fix it by adding a boolean that\nindicates whether or not the P2P-Device should be added to the\nbinding, and handle that in the binding iterator. That way, the\nstation interface cannot re-add the P2P-Device to the binding\nwhen that isn't active."
