CVE-2026-10658

CVE-2026-10658 affects Zephyr’s Bluetooth Host ISO RX path, specifically bt_iso_recv() in subsys/bluetooth/host/iso.c. The vulnerability arises from missing minimum length checks for SDU headers when processing PB=START/SINGLE, allowing a malformed HCI ISO payload to bypass the inner header lengt...

CVE-2026-10658 Bluetooth Host ISO RX Missing SDU Header Length Validation in bt_iso_recv() Leads to DoS

A missing length validation in the Zephyr Bluetooth Host ISO receive path can be triggered by malformed HCI ISO data. In btisorecv subsys/bluetooth/host/iso.c, when processing PB=START/SINGLE fragments, the code pulls a TS SDU header 8 bytes, ts=1 or a non-TS SDU header 4 bytes, ts=0 without firs...
