CVE-2024-50201: drm/radeon: Fix encoder->possible_clones

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: 0.21% (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 1a235af0216411a32ab4db54f7bd19020b46c86d, 28127dba64d8ae1a0b737b973d6d029908599611, 68801730ebb9393460b30cd3885e407f15da27a9; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1.

Low priority for now. Upgrade to Linux Linux 1a235af0216411a32ab4db54f7bd19020b46c86d, 28127dba64d8ae1a0b737b973d6d029908599611, 68801730ebb9393460b30cd3885e407f15da27a9; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1 or later.

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Fix encoder->possible_clones Include the encoder itself in its possible_clones bitmask. In the past nothing validated that drivers were populating possible_clones correctly, but that changed in commit 74d2aacbe840 ("drm: Validate encoder->possible_clones"). Looks like radeon never got the memo and is still not following the rules 100% correctly. This results in some warnings during driver initialization: Bogus possible_clones: [ENCODER:46:TV-46] possible_clones=0x4 (full encoder mask=0x7) WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drm_mode_config.c:615 drm_mode_config_validate+0x113/0x39c ... (cherry picked from commit 3b6e7d40649c0d75572039aff9d0911864c689db)

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.

EPSS, last 120 days

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 researchers

Finders, 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.
