Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-011010)

high Nessus Plugin ID 308895

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-2026-011010 advisory.

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

 staging: media: tegra-video: fix device_node use after free

 At probe time this code path is followed:

 * tegra_csi_init
 * tegra_csi_channels_alloc
 * for_each_child_of_node(node, channel) -- iterates over channels
 * automatically gets 'channel'
 * tegra_csi_channel_alloc()
 * saves into chan->of_node a pointer to the channel OF node
 * automatically gets and puts 'channel'
 * now the node saved in chan->of_node has refcount 0, can disappear
 * tegra_csi_channels_init
 * iterates over channels
 * tegra_csi_channel_init -- uses chan->of_node

 After that, chan->of_node keeps storing the node until the device is removed.

 of_node_get() the node and of_node_put() it during teardown to avoid any risk.

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.
