Root-owned file overwrite via symlink following
Published Sep 3, 2026 · Updated Sep 3, 2026
Path-handling weakness in Joe Sylve LiME 1.12.0 and earlier allows local users to overwrite root-owned files via an output-path symlink. The disk acquisition path is opened without destination validation or O_NOFOLLOW, so a precreated symbolic link is followed and its target is truncated with the memory stream. Exploitation requires control of the output directory before a privileged acquisition, and the bounded consequence is corruption of an attacker-chosen root-owned file.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
