Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992396)

medium Nessus Plugin ID 280443

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-2025-992396 advisory.

In the Linux kernel, the following vulnerability has been resolved:

tpm: tpm_crb: Add the missed acpi_put_table() to fix memory leak

In crb_acpi_add(), we get the TPM2 table to retrieve information like start method, and then assign them to the priv data, so the TPM2 table is not used after the init, should be freed, call acpi_put_table() to fix the memory leak.

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.
