CVE-2025-37870: drm/amd/display: prevent hang on link training fail

MediumCVSS 5.5 · v3.1—No exploit Fix available

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: 0.30% (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 0363c03672cd3191f037905bf981eb523a3b71b1, 04bf4f2a497e9877c425c5124652e61fb8a1a0aa, 52cdc47cf6519e2912a34d29b7eeb3f10ca85efa.

Low priority for now. Upgrade to Linux Linux 0363c03672cd3191f037905bf981eb523a3b71b1, 04bf4f2a497e9877c425c5124652e61fb8a1a0aa, 52cdc47cf6519e2912a34d29b7eeb3f10ca85efa or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: prevent hang on link training fail [Why] When link training fails, the phy clock will be disabled. However, in enable_streams, it is assumed that link training succeeded and the mux selects the phy clock, causing a hang when a register write is made. [How] When enable_stream is hit, check if link training failed. If it did, fall back to the ref clock to avoid a hang and keep the system in a recoverable state.
