Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-390793)
medium Nessus Plugin ID 267065
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-390793 advisory.In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix regression with module command in stack_trace_filter
When executing the following command:
# echo write*:mod:ext3 > /sys/kernel/tracing/stack_trace_filter
The current mod command causes a null pointer dereference. While commit 0f17976568b3f (ftrace: Fix regression with module command in stack_trace_filter) has addressed part of the issue, it left a corner case unhandled, which still results in a kernel crash.
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected kernel package.See Also
