Unverified50% confidenceOpinionExact time
Linux namespaces and cgroups can be used to restrict process capabilities, and combined with mechanisms such as seccomp they form a defense-in-depth system, so that even if an attacker exploits a vulnerability to gain code execution, it is difficult to further escalate privileges or move laterally.

UnverifiedA network namespace is Linux's mechanism for isolating the network stack; each namespace has its own network interfaces, routing table, firewall rules, and port space; attacking across namespaces requires a kernel vulnerability rather than a simple configuration change.72% similarUnverifiedVulnerabilities at the baseband level can often bypass multiple layers of operating system protection; in theory, attackers may be able to achieve remote intrusion without any user interaction.71% similarUnverifiedLinux security modules such as seccomp and AppArmor can further tighten permissions at the system call level.69% similarUnverifiedEven if a user-mode program has a serious vulnerability, the impact is usually confined to that process; but once a kernel vulnerability is exploited, the attacker can obtain the system's highest privileges, and the scope of impact is the entire machine.67% similarUnverifiedA heap overflow is a memory safety vulnerability in which an attacker corrupts adjacent memory structures by writing data beyond the boundaries of allocated heap memory, potentially achieving arbitrary code execution or control of program flow.67% similar
