The vulnerability does not allow remote code execution or compromise of running containers, and it only exposes files temporarily present in the build context. Therefore, while it can lead to information disclosure, the scope and impact are limited to local users with concurrent access, making the overall risk moderate.",

Specifically, the use of process isolation and memory protection ensures memory integrity by isolating processes and enforcing memory protection mechanisms that limit an attacker\u0027s ability to exploit or read memory.

This attack is a more sophisticated variant of CVE-2019-16884, which was a flaw that allowed an attacker to trick runc into writing the LSM process labels for a container process into a dummy tmpfs file and thus not apply the correct LSM labels to the container process. The mitigation applied for CVE-2019-16884 was fairly limited and effectively only caused runc to verify that when we write LSM labels that those labels are actual procfs files.",
