CVE-2026-11893: use-after-free in zephyrproject zephyrCVE-2026-11893
0

CVE-2026-11893 is a use-after-free vulnerability in the Zephyr Bluetooth HCI driver for Bouffalo Lab on-chip BLE controllers (BL60x/BL70x/BL61x). The driver violates the buffer ownership contract by unconditionally freeing a buffer on error, leading to a double free and premature freeing of a parent buffer. This causes use-after-free and corruption of the shared net_buf pool, resulting in denial of service via BLE stack crash or memory corruption. The issue arises on the host-to-controller transmit path under error conditions such as controller send failure or unsupported packet types. It affects Zephyr versions 4.4.0 and 4.4.1. The CVSS score is 5.9 (medium severity).
