Vulnerability Title
staging: media: tegra-video: fix of_node_put() on VIP parse errors
Source: CVE Program / CVE List V5
Vulnerability 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.
