| | | | | [AI summary] The text describes an exploit that leverages memory layout vulnerabilities in the Linux kernel. The attacker opens two files, maps them into memory, and uses a buffer overflow to overwrite the `f_mapping` field of a file structure. This allows the attacker to redirect file operations to a malicious location, potentially leading to privilege escalation. | |

| | | | | In all the playing around I've been doing with Linux kernel modules, I decided to see what would happen if you tried to load one from a Docker container. It turns out that privileged containers (or just those with CAP_SYS_MODULE) are able to use the sys_init_module() and sys_finit_module() syscalls - which are what's used to load kernel modules. As all containers share their kernel with the host (unlike VMs), this clearly results in yet another complete system compromise. | |
