CVE-2026-93223

/// Technical description

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

staging: media: tegra-video: fix of_node_put() on VIP parse errors

tegra_vip_channel_of_parse() initializes np from dev->of_node without

taking a reference, but its error paths drop one through the

err_node_put label. This underflows the refcount of the VIP device's

OF node when endpoint parsing fails on a malformed device tree.

The only reference the function takes on np is the success-path

of_node_get() stored in vip->chan.of_node, and that one is already

released by the tegra_vip_init() error path and by tegra_vip_exit().

Return errors directly instead of jumping to the bogus cleanup label.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
