io_uring Same Type Object Reuse Privilege Escalation
Posted Feb 1, 2023
Authored by h00die, Mathias Krause, Ryota Shiga | Site metasploit.com

This Metasploit module exploits a bug in io_uring leading to an additional put_cred() that can be exploited to hijack credentials of other processes. This exploit will spawn SUID programs to get the freed cred object reallocated by a privileged process and abuse them to create a SUID root binary that will pop a shell. The dangling cred pointer will, however, lead to a kernel panic as soon as the task terminates and its credentials are destroyed. We therefore detach from the controlling terminal, block all signals and rest in silence until the system shuts down and we get killed hard, just to cry in vain, seeing the kernel collapse. The bug affected kernels from v5.12-rc3 to v5.14-rc7. More than 1 CPU is required for exploitation. Successfully tested against Ubuntu 22.04.01 with kernel 5.13.12-051312-generic.
