CVE-2026-99012 Bluetooth: ISO: Serialize concurrent connect calls

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Serialize concurrent connect calls isosockconnect checks the socket state before taking the socket lock and drops the lock again before setting up a connection. Two callers can both pass the admission check while...

CVE-2026-99011

The Linux kernel is affected by a slab-use-after-free vulnerability in the Bluetooth SCO component. The issue arises because sco_recv_scodata() upgrades a weak back-pointer to a strong reference under hdev->lock, but the pointer is cleared by sco_conn_free() without holding that same lock. Thi...

CVE-2026-99010 Bluetooth: RFCOMM: free the skb when the DLC has no owner

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: free the skb when the DLC has no owner rfcommrecvdata hands the skb to d-dataready and returns 0 without freeing it, so the callback owns the skb from that point on. The tty implementation frees it when the DLC...

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...

CVE-2026-99009 Bluetooth: RFCOMM: connect the session socket without rfcomm_mutex

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: connect the session socket without rfcommmutex An RFCOMM connect issued while a BR/EDR link is being authenticated makes lockdep report a circular dependency, and the reported cycle is a real AB/BA between...

CVE-2026-99009

The Linux kernel contains a circular locking dependency vulnerability in the Bluetooth RFCOMM component. The issue arises because an RFCOMM connect() from userspace acquires rfcomm_mutex before hdev->lock, while the HCI event path (via rfcomm_security_cfm()) acquires them in the opposite order...

CVE-2026-99008

The Linux kernel contains a NULL pointer dereference vulnerability in the Bluetooth RFCOMM component. The issue occurs in rfcomm_dev_shutdown() when an RFCOMM tty is closed. Specifically, rfcomm_dev_add() adds a device to the list before registering the tty device; if registration fails, dev->...
