Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986914)

high Nessus Plugin ID 268333

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-2025-986914 advisory.

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

EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info

The memory for llcc_driv_data is allocated by the LLCC driver. But when it is passed as the private driver info to the EDAC core, it will get freed during the qcom_edac driver release. So when the qcom_edac driver gets probed again, it will try to use the freed data leading to the use-after-free bug.

Hence, do not pass llcc_driv_data as pvt_info but rather reference it using the platform_data pointer in the qcom_edac driver.

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.
