CVE-2025-68304

CVE-2025-68304 concerns the Linux kernel Bluetooth path. The issue occurs in the RX path of HCI protocol handling where the hci_conn object may be concurrently modified/deleted while still being looked up, enabling a use-after-free in certain code paths. The bug was addressed by moving the lookup...

CVE-2025-68304 Bluetooth: hci_core: lookup hci_conn on RX path on protocol side

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: lookup hciconn on RX path on protocol side The hdev lock/lookup/unlock/use pattern in the packet RX path doesn't ensure hciconn is not concurrently modified/deleted. This locking appears to be leftover from...

CVE-2025-68298 Bluetooth: btusb: mediatek: Avoid btusb_mtk_claim_iso_intf() NULL deref

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: mediatek: Avoid btusbmtkclaimisointf NULL deref In btusbmtksetup, we set btmtkdata-isopktintf to: usbifnumtoifdata-udev, MTKISOIFNUM That function can return NULL in some cases. Even when it returns NULL, though...

CVE-2025-68298

CVE-2025-68298 involves a NULL dereference in Linux kernel Bluetooth code for Mediatek BTUSB. In btusb_mtk_setup(), btmtk_data->isopkt_intf can be NULL after usb_itf lookup (usb_ifnum_to_if). The code erroneously calls btusb_mtk_claim_iso_intf() even when isopkt_intf is NULL, leading to a cras...
