CVE-2026-93223: staging: media: tegra-video: fix of_node_put() on VIP parse errors

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 1295ba29ac590bbb5c4a586afd408018168af10b, 656d047dc0c29c0964d840217a0593f16aa9bc5e, 7393372f79db940acff206b43e2905685a0c57ad; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 Release Notes.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1295ba29ac590bbb5c4a586afd408018168af10b, 656d047dc0c29c0964d840217a0593f16aa9bc5e, 7393372f79db940acff206b43e2905685a0c57ad; azl3 kernel 6.6.150.1-1 on Azure Linux 3.0 Release Notes or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
