The following mitigations prevent only our specific exploit from working (but other exploitation techniques may exist); to completely fix this vulnerability, the kernel must be patched. Part of the exploit is to create a new user namespace. There have been some niche changes that include more exploits and it has an option to download the detected exploit code directly from Exploit DB. The bug is in Linux’s seq_file interface, and “Sequoia sempervirens” is a tree that has wide-spreading roots: a pun on the bug’s deep directory tree that yields root privileges.
