How severe is CVE-2026-72009?

No CVSS score has been assigned to CVE-2026-72009 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-72009?

CVE-2026-72009 affects the following packages: Kernel (Linux). Ecosystems affected: Linux.

How do I fix CVE-2026-72009?

Update Kernel to 6.18.42 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-72009 is resolved across your whole dependency graph.

How do I detect CVE-2026-72009 in my Linux dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Kernel. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2026-72009 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2026-72009?

O3 pinpoints whether CVE-2026-72009 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2026-72009 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-72009 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Linux packages — download data is not available via public APIs for these ecosystems.

Description

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

pmdomain: imx93-blk-ctrl: Extract PHY as shared domain for DSI/CSI

The MIPI DSI and CSI domains share control bits for clock and reset, which can lead to incorrect behavior if one domain disables the shared resource while the other is still active.

To fix the issue, introduce a shared MIPI PHY power domain to own the common resources and make DSI and CSI its subdomains. This ensures the shared bits are properly managed and not disabled while still in use.
