CVE-2026-98735

A use-after-free vulnerability exists in the Linux kernel Bluetooth hci_core component. The issue occurs because hci_chan_sent() selects a channel under RCU but releases the read lock before accessing chan->conn. This allows a disconnect command timeout to trigger hci_chan_del(), which unlinks...
