drm/mcde: Fix refcount leak in mcde_dsi_bind
Noroxi assessment
Priority: Monitor (action score 22/100)
- 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: 0.24% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 3123ae6fdd4013d24a3a4877084b14e917faae5c, 32c827e30bb44ae809950a9efab59e98e44d30e5, 3a149169e4a2f9127022fec6ef5d71b4e804b3b9.
Low priority for now. Upgrade to Linux Linux 3123ae6fdd4013d24a3a4877084b14e917faae5c, 32c827e30bb44ae809950a9efab59e98e44d30e5, 3a149169e4a2f9127022fec6ef5d71b4e804b3b9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: drm/mcde: Fix refcount leak in mcde_dsi_bind Every iteration of for_each_available_child_of_node() decrements the reference counter of the previous node. There is no decrement when break out from the loop and results in refcount leak. Add missing of_node_put() to fix this.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
No commit or PR link among the references.
Credits
All researchersFinders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.
No credits in the CNA record.
Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
