CVE-2025-12970

CVSS v2.0

9.0

High

VectorAV:N/AC:L/Au:S/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Fluent Bit versions (affected versions not specified)
Description The extract name function within the in docker input plugin of Fluent Bit contains a buffer overflow issue. This occurs because the function copies container names into a fixed-size stack buffer without proper length validation. An attacker capable of creating containers or controlling container names can exploit this by providing a long name, causing the buffer to overflow. This can lead to a process crash or potentially arbitrary code execution.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
