Kernel subsystem within OpenHarmony-v3.1.4 and prior versions in kernel_liteos_a has a kernel stack overflow vulnerability when call SysClockGetres. 4 bytes padding data from kernel stack are copied to user space incorrectly and leaked.
AnalysisAI
Kernel subsystem within OpenHarmony-v3.1.4 and prior versions in kernel_liteos_a has a kernel stack overflow vulnerability when call SysClockGetres. Rated low severity (CVSS 3.3), this vulnerability is low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. Kernel subsystem within OpenHarmony-v3.1.4 and prior versions in kernel_liteos_a has a kernel stack overflow vulnerability when call SysClockGetres. 4 bytes padding data from kernel stack are copied to user space incorrectly and leaked. Affected products include: Openharmony, Openatom Openharmony.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
