0 CVE-2026-19738 is a denial-of-service vulnerability in the Zephyr project's Bluetooth Link Layer Control Procedure (LLCP) implementation for Connected Isochronous Stream (CIS) creation. The flaw causes memory nodes to be retained and orphaned without release upon receiving invalid PDUs, leading to resource exhaustion. An attacker within radio range can exploit this without authentication or encryption by sending crafted LL Control PDUs. The impact is limited to availability, causing controller fatal errors or stalled flow control requiring system reboot to recover.
