In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_sync: Fix accept list UAF during suspend

hci_update_event_filter_sync() walks hdev->accept_list while sending a synchronous HCI command for each remote-wakeup device. The suspend path holds hdev->req_lock, but accept-list updates are serialized by hdev->lock. Consequently, remove_device() can free the current list entry during the controller wait.

The following interleaving causes the use-after-free:

hci_update_event_filter_sync() remove_device() fetch accept-list entry hci_set_event_filter_sync() wait for controller response hci_dev_lock() list_del() kfree() hci_dev_unlock() read the freed list.next

WID-SEC-W-2026-3211 — Linux Kernel: Mehrere Schwachstellen

Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Linux Kernel ausnutzen, um Speicherfehler und Kernel-Abstürze beziehungsweise Denial-of-Service-Zustände auszulösen, Speicher außerhalb vorgesehener Grenzen auszulesen sowie in einzelnen Fällen weitere Sicherheitsauswirkungen zu verursachen.
