CVE-2024-46813: drm/amd/display: Check link_index before accessing dc->links[]

Noroxi assessment

Priority: Monitor (action score 31/100)

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: 0.25% (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 032c5407a608ac3b2a98bf4fbda27d12c20c5887, 8aa2864044b9d13e95fe224f32e808afbf79ecdf, 8ad4c2cf6c1af18f556e5c591fb313b2982ddf60.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 032c5407a608ac3b2a98bf4fbda27d12c20c5887, 8aa2864044b9d13e95fe224f32e808afbf79ecdf, 8ad4c2cf6c1af18f556e5c591fb313b2982ddf60 or later.

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.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
