CVE-2026-14607: Memory Corruption in RT-Thread
A weakness has been identified in RT-Thread up to 5.0.2. This affects the function sys_getaddrinfo of the file components/lwp/lwp_syscall.c. Executing a manipulation of the argument ai_addr can lead to memory corruption. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. The pull request to fix this issue awaits acceptance.
AI Analysis
Technical Summary
This vulnerability in RT-Thread up to version 5.0.2 involves improper handling of the ai_addr argument in the sys_getaddrinfo function, leading to potential memory corruption. The attack vector is local with low complexity and no user interaction required. The vulnerability could allow an attacker with local privileges to corrupt memory, potentially impacting system stability or security. Although an exploit is publicly available, there is currently no official patch or remediation released; a pull request with a fix is pending acceptance.
Potential Impact
Successful exploitation can cause memory corruption on affected RT-Thread versions, which may lead to system instability or compromise. The attack requires local access and low privileges, increasing the risk in environments where untrusted local users exist. No remote exploitation or user interaction is needed. No known exploits are reported in the wild at this time.
Mitigation Recommendations
No official patch or fix is currently available. A pull request addressing the issue is awaiting acceptance. Users should monitor the vendor's advisories for the release of an official fix. Until then, restrict local access to trusted users only to reduce risk.
