CVE-2025-38159

Estado: AnalizadaAlta (7.1)—

In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw88: fix the 'para' buffer size to avoid reading out of bounds

Set the size to 6 instead of 2, since 'para' array is passed to 'rtw_fw_bt_wifi_control(rtwdev, para[0], &para[1])', which reads 5 bytes:

Detected using the static analysis tool - Svace.
