Unity Linux 20.1070a Security Update: kernel (UTSA-2025-384653)

high Nessus Plugin ID 267293

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-2025-384653 advisory.

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

 usb: musb: sunxi: Fix accessing an released usb phy

 Commit 6ed05c68cbca (usb: musb: sunxi: Explicitly release USB PHY on exit) will cause that usb phy @glue->xceiv is accessed after released.

 1) register platform driver @sunxi_musb_driver // get the usb phy @glue->xceiv sunxi_musb_probe() -> devm_usb_get_phy().

 2) register and unregister platform driver @musb_driver musb_probe() -> sunxi_musb_init() use the phy here //the phy is released here musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy()

 3) register @musb_driver again musb_probe() -> sunxi_musb_init() use the phy here but the phy has been released at 2).
 ...

 Fixed by reverting the commit, namely, removing devm_usb_put_phy() from sunxi_musb_exit().

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.
