CVE-2026-97432 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix P2P-Device binding handling Our binding handling for P2P-Device can run into the following scenario, as observed by our testing: - a station interface is connected on some channel - the P2P-Device does a remain-on-channel (ROC) on that channel - the ROC ends, and the P2P-Device is removed from the binding, but the phy_ctxt pointer is left around as a PHY cache so we don't need to recalibrate to the channel again and again in case it's not shared - a binding update by the station interface, even a removal, will re-add the P2P-Device to the binding - the P2P-Device is removed, which removes the PHY context, but it's still in the binding so the firmware crashes Since the P2P device is removed from the binding and only re- added by unrelated code, but we want to keep the phy_ctxt around as a cache for future ROC usage, fix it by adding a boolean that indicates whether or not the P2P-Device should be added to the binding, and handle that in the binding iterator. That way, the station interface cannot re-add the P2P-Device to the binding when that isn't active..
