CVE-2026-10675 Bluetooth Mesh PB-ADV: invalidated provisioning link kept alive indefinitely, blocking (re)provisioning (DoS)

In Zephyr's Bluetooth Mesh PB-ADV provisioning bearer subsys/bluetooth/mesh/pbadv.c, provmsgrecv rescheduled the provisioning protocol watchdog timer unconditionally at the top of the function, before the FCS check and before the ADVLINKINVALID check. Once a provisioning attempt fails, provfailed...

CVE-2026-10675

Zephyr Project Bluetooth Mesh PB-ADV vulnerability (CVE-2026-10675) in prov_msg_recv() reschedules the provisioning watchdog timer unconditionally at the top of the function, before FCS and ADV_LINK_INVALID checks. If a provisioning attempt fails (ADV_LINK_INVALID set), a malicious, unauthenticat...

CVE-2026-63871

A flaw was found in the Linux kernel's Bluetooth ISO subsystem. This vulnerability, a data-race, occurs because certain functions access socket-related data without proper synchronization. Specifically, isoconnectbis, isoconnectcis, isolistenbis, and isoconnbigsync can read critical fields while...

kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp

A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP implementation. A remote Bluetooth Low Energy BLE device can exploit this by sending a specially crafted L2CAP ECRED reconfiguration response. This can lead to the corruption of the channel list,...

CVE-2026-63976

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol implementation. A remote attacker, acting as a peer, could exploit a vulnerability where the system fails to clear a channel identifier after a successful Enhanced Credit Based Mode ECRED...

CVE-2026-63946

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. This vulnerability, known as a Use-After-Free, occurs because the system attempts to use a memory area after it has been released, which can lead to unpredictable behavior. A malicious actor could potentially explo...
