cve CVE-2018-5333 2 sources, 2 claims · Watch

Metasploit exploit modules writes:
This module attempts to gain root privileges on Linux systems by abusing a NULL pointer dereference in the `rds_atomic_free_op` function in the Reliable Datagram Sockets (RDS) kernel module (rds.ko). Successful exploitation requires the RDS kernel module to be loaded. If the RDS module is not blacklisted (default); then it will be loaded automatically. This exploit supports 64-bit Ubuntu Linux systems, including distributions based on Ubuntu, such as Linux Mint and Zorin OS. Target offsets are available for: … the claim
