CVE-2026-90286: drm/amdgpu/gfx6: Use PFP on the compute queues too

Noroxi assessment

Priority: Monitor (action score 35/100)

  • 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: 0.17% (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 2aa869c6b23e0b1b7f39f762618852811d75deb9, 60f20946cd318518ddc2c0da12103c666b2b9564, 8d752f1bb73fabe5a425acbf5c767c0fe68bf3c5.

Low priority for now. Upgrade to Linux Linux 2aa869c6b23e0b1b7f39f762618852811d75deb9, 60f20946cd318518ddc2c0da12103c666b2b9564, 8d752f1bb73fabe5a425acbf5c767c0fe68bf3c5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx6: Use PFP on the compute queues too On GFX6, the compute rings use the same CP path as the graphics ring. The only difference is that they don't support draw commands. (As opposed to GFX7 and newer which have a separate command parser that is called MEC for compute queues.) This means that we have to take into consideration that the PFP also exists on compute queues on GFX6: Use PFP for register writes on both graphics and compute queues. In the pipeline sync, use the PFP to wait for the previous fence (and not the ME) to prevent the PFP from starting to execute the next submission while the ME is still in the previous submission. After a VM flush, emit PFP_SYNC_ME on compute queues as well.

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.
