NXP moal.ko Wi-Fi driver 5.1.7.10 FW version from v17.92.1.p149.43 To v17.92.1.p149.157 was discovered to contain a buffer overflow via the mod_para parameter in the woal_init_module_param function.
AnalysisAI
Buffer overflow in NXP moal.ko Wi-Fi driver versions 5.1.7.10 with firmware v17.92.1.p149.43 through v17.92.1.p149.157 allows local privileged attackers to cause denial of service and potentially corrupt memory via the mod_para parameter in the woal_init_module_param function. The vulnerability requires high-privilege access and cannot be triggered remotely, but public exploit code exists and SSVC analysis indicates non-automatable exploitation with partial technical impact.
Technical ContextAI
The moal.ko driver is a Linux kernel module for NXP Wi-Fi hardware that handles module parameter initialization through the woal_init_module_param function. The vulnerability stems from improper bounds checking (CWE-120: Buffer Copy without Checking Size of Input) in the mod_para parameter processing, allowing an attacker with elevated privileges to write beyond allocated buffer boundaries. The affected versions span a narrow firmware range (v17.92.1.p149.43 to v17.92.1.p149.157), suggesting the vulnerability was introduced and fixed within a specific development cycle. This is a kernel-space driver vulnerability, meaning exploitation occurs at the lowest privilege level accessible through privileged user processes.
RemediationAI
Update NXP moal.ko driver and firmware to a version beyond v17.92.1.p149.157 by consulting NXP release note RN00104 (https://www.nxp.com/docs/en/release-note/RN00104.pdf) for the appropriate firmware package and driver version for your platform. If immediate updates are unavailable, restrict the ability to load or modify kernel modules to only trusted system administrators by enforcing strict Linux kernel module loading policies (disable kernel module loading via sysctl kernel.modules_disabled=1 or SELinux/AppArmor policies that prevent unprivileged module parameter modification). Monitor system logs for unexpected woal_init_module_param invocations or kernel module parameter changes. Be aware that completely disabling module loading may impact driver hot-patching or runtime configuration needs, so coordinate with system operations before applying this control.
