Description
CVE-2026-98389 is a vulnerability in the Linux kernel's AMDGPU driver where the gfx switch_power_profile function is invoked during GPU reset before the reset completes. This leads to an assertion error due to register access without releasing the GPU reset semaphore. The issue has been fixed in later commits.
