Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已解决以下漏洞： wifi: iwlwifi: mvm：修复 P2P-Device 绑定处理逻辑 我们针对 P2P-Device 的绑定处理逻辑存在一个漏洞，根据我们的测试观察，可能引发以下场景： 一个站点接口（station interface）已连接到某个信道； P2P-Device 在该信道上执行“保持在线信道”（remain-on-channel, ROC）操作； ROC 操作结束，P2P-Device 从绑定列表中移除；但 指针仍保留，作为 PHY 缓存，以避免在后续重新需要该信道

Source: CVE Program / CVE List V5
Vulnerability Description
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.
