Overview
CVE-2026-90213 is a known-severity vulnerability. It was published on September 17, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
firewire: core: fix memory leak in error path of build_tree()
In the error path of build_tree(), node instances can remain in the local
linked list when the function returns.
Whenever an invalid value is detected in the self ID sequence, each
allocated node instance is either an entry in the linked list or an
entry in the ports array of its parent node. Therefore, the allocate
node instances can be safely released by traversing the linked list from
its head.
Release the remaining node instances with for_each_fw_node() before
returning to the caller.

How can CyberStrike help with CVE-2026-90213?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-90213 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
