CVE-2026-98733

The Linux kernel contains a vulnerability in the Bluetooth subsystem within the hci_core component. The hci_queue_iso() function incorrectly calls __skb_queue_tail() without holding the conn->data_q.lock, leading to a race condition where a transmit worker can concurrently remove packets using...

CVE-2026-98633

The Linux kernel contains a memory leak vulnerability in the Bluetooth btnxpuart component within the nxp_process_fw_dump() function. When CONFIG_DEV_COREDUMP is disabled, the hci_devcd_append() function returns -EOPNOTSUPP without freeing its skb argument , resulting in a leaked cloned skb. This...

CVE-2026-98633 Bluetooth: btnxpuart: Fix skb leak in nxp_process_fw_dump()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btnxpuart: Fix skb leak in nxpprocessfwdump When CONFIGDEVCOREDUMP=n, hcidevcdappend returns -EOPNOTSUPP without freeing its skb argument. This leaks the cloned skb and also prevents nxpsetindreset from being called to...

CVE-2026-98632 Bluetooth: mgmt: Dequeue pending mesh_send_sync entries on cancel

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: Dequeue pending meshsendsync entries on cancel In sendcancel, pending meshtx objects are removed from the hdev-meshpending list and freed via meshsendcomplete. However, if a mesh transmission was already queued...

CVE-2026-98632

A use-after-free vulnerability exists in the Linux kernel Bluetooth management component. The issue occurs because send_cancel() frees mesh_tx objects via mesh_send_complete() while the hdev->cmd_sync_work_list may still retain a raw pointer to those objects. When hci_cmd_sync_work processes t...

CVE-2026-98602

The Linux kernel contains a vulnerability in the Bluetooth BNEP (Bluetooth Network Encapsulation Protocol) implementation. Specifically, the bnep_rx_frame() and bnep_ctrl_frame() functions in net/bluetooth/bnep/core.c fail to properly verify the existence of BNEP headers and extension headers, le...

CVE-2026-98600

The Linux kernel Bluetooth RFCOMM component contains a vulnerability in rfcomm_recv_frame() related to how it handles short EA=0 frames. When a frame with an extended 2-byte length field (requiring a 5-byte minimum) arrives as a 4-byte frame, the initial length check passes, but subsequent proces...
