Low risk2th percentile - higher than 2% of all known CVEs
Summary
A weakness has been identified in RT-Thread up to version 5.0.2 in the function sys_getaddrinfo in file components/lwp/lwp_syscall.c. Manipulation of the ai_addr argument can lead to memory corruption. The attack requires local access and the exploit is publicly available.
Risk Assessment
The organization is at risk of local attacks causing memory corruption, potentially leading to system crashes or privilege escalation. The public exploit increases the likelihood of exploitation.
Recommendation
Immediately apply the available patch or update RT-Thread to a version above 5.0.2 once the fix is released. Until then, restrict local access to the system.
