Description
simpleinit on Linux systems does not close a read/write FIFO file descriptor before creating a child process, which allows the child process to cause simpleinit to execute arbitrary programs with root privileges.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
