| Title | RT-Thread 5.1.0 Improper Handling of Parameters |
|---|
| Description | A vulnerability in the sys_sendto system call in the Smart version of RT-Thread v5.1.0. This vulnerability stems from insufficient pointer validation in the sockaddr_tolwip function, which is called by sys_sendto. The code only checks if the pointer is NULL but fails to verify whether the pointer points to valid memory. If exploited by a compromised user thread, this issue could lead to severe security consequences, including kernel crashes and potential unauthorized memory access. |
