What is CVE-2025-5865?

A memory corruption vulnerability has been identified in the sys_select function within the RT-Thread 5.1.0 operating system. This issue arises from improper handling of the timeout parameter in the Parameter Handler component, specifically in the lwp_syscall.c file. Developers must ensure that the timeout parameter is validated for correct access in kernel mode, as failure to do so can lead to significant security risks. Attackers exploiting this weakness may manipulate memory, potentially compromising system integrity.
