CVE-2026-11368 Use-after-free in Bluetooth host ATT TX completion on disconnect mid-transfer

The Bluetooth host ATT layer subsys/bluetooth/host/att.c associates each in-flight ATT TX buffer with its owning channel via the static txmetadatastorage array data-attchan = chan. When a buffer's last reference is dropped, its net-buf destroy callback defers the completion handling to the system...

CVE-2026-11368

Summary of CVE-2026-11368 details: The Bluetooth host ATT layer (att.c) ties in-flight ATT TX buffers to channels via tx_meta_data_storage[]. When a buffer is freed, completion handling defers to a workqueue path (att_tx_destroy -> att_tx_destroy_work_handler -> att_on_sent_cb -> bt_att_...

CVE-2026-10774

Zephyr's Bluetooth Mesh subnet key management leaks one PSA Crypto key slot on every subnet-key teardown. In subsys/bluetooth/mesh/subnet.c, netkeyscreate imports the Private Beacon Key into a PSA key slot under CONFIGBTMESHPRIVBEACONS enabled by default, but subnetkeysdestroy guarded the matchin...

CVE-2026-10774

Summary. CVE-2026-10774 affects Zephyr’s Bluetooth Mesh implementation. The vulnerability arises when subnet keys are torn down: net_keys_create() imports the Private Beacon Key into a PSA key slot, but subnet_keys_destroy() did not balancedly free the slot due to a removed Kconfig guard. This cr...

CVE-2026-64549

A flaw was found in the Linux kernel's Bluetooth bpa10x driver. This vulnerability allows a malicious Bluetooth device to trigger an out-of-bounds read in the bpa10xsetup function by sending a specially crafted one-byte or non-NUL-terminated response. This can lead to information disclosure, wher...

CVE-2026-10772

DUPLICATE This CVE Record has been rejected by the Zephyr Project CNA. CVE-2026-10772 was assigned to a vulnerability already covered by CVE-2026-2411, which was assigned earlier for the same defect: the Bluetooth GATT notify/indicate paths check the permissions of the Characteristic Declaration...

CVE-2026-2411

Zephyr's Bluetooth host declares a GATT characteristic as two consecutive attributes: a Characteristic Declaration whose permission is hard-coded to BTGATTPERMREAD, and a Characteristic Value attribute that carries the application-specified security permissions e.g. BTGATTPERMREADENCRYPT /...
