0 CVE-2026-12999 is a denial-of-service vulnerability in the Infineon Airoc Wi-Fi driver within the Zephyr project. The vulnerability causes a permanent memory leak of network buffers on transmit failures, eventually exhausting the buffer pool and causing loss of Wi-Fi connectivity until the device is rebooted. The issue arises from failure to release allocated buffers on synchronous send errors. The vulnerability affects Zephyr versions from 3.6.0 up to but not including 4.4.2. The impact is availability-only, with no confidentiality or integrity effects. Exploitation requires complex conditions and is not known to be exploited in the wild. A fix has been implemented to properly release buffers on failure. Join the discussion | CVE Database V5 | 08/22/2026, 20:35:40 UTC Added: 08/22/2026, 20:52:41 UTC |
