➀ Security researchers have revealed a serious vulnerability in ASUS Armoury Crate software;

➁ The flaw allows hackers to gain admin access to computers;

➂ The vulnerability is tracked as CVE-2025-3464 and affects the As103.sys functionality of the software.

➀ Io_uring was introduced in 2019 to improve the efficiency and flexibility of input and output operations on Linux, but it also created critical blind spots for Linux security tools.

➁ Security researchers have discovered that io_uring operations can completely evade conventional system call monitoring, leading to undetectable activities.

➂ A rootkit called Curing was built to exploit this vulnerability, which can execute commands, read files, and interact with the network without detectable system calls.
