CVE-2026-99010

The Linux kernel Bluetooth RFCOMM component contains a memory leak vulnerability. The issue occurs in rfcomm_recv_data() when a Data Link Control (DLC) has no owner (e.g., after rfcomm_sock_destruct() clears d->owner but before the session closes). In the socket implementation, the skb is hand...
