Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx: disable gfx9 cp_ecc_error_irq only when enabling legacy gfx ras gfx9 cp_ecc_error_irq is only enabled when legacy gfx ras is assert. So in gfx_v9_0_hw_fini, interrupt disablement for cp_ecc_error_irq should be executed under such condition, otherwise, an amdgpu_irq_put calltrace will occur.

Recommended fix High confidence

Linux kernel 5.4.243 / 5.10.180 / 5.15.112 / 6.1.29 or later (depending on your current branch)

  1. 1. Identify the currently running Linux kernel version using `uname -r`
  2. 2. Check which version branch your current kernel belongs to (e.g., 5.4.x, 5.10.x, 5.15.x, or 6.1.x)
  3. 3. For kernels >= 4.2 and < 5.4.243: upgrade to kernel version 5.4.243 or later
  4. 4. For kernels >= 5.5 and < 5.10.180: upgrade to kernel version 5.10.180 or later
  5. 5. For kernels >= 5.11 and < 5.15.112: upgrade to kernel version 5.15.112 or later
  6. 6. For kernels >= 5.16 and < 6.1.29: upgrade to kernel version 6.1.29 or later
  7. 7. Reboot the system to load the fixed kernel
  8. 8. Verify the fix is applied by checking the gfx_v9_0_hw_fini function in /usr/src/linux/drivers/gpu/drm/amd/amdgpu/gfx_v9_0.c contains the conditional check before amdgpu_irq_put for cp_ecc_error_irq
Caveat Kernel upgrades may introduce regressions; ensure compatibility with userspace drivers and specific hardware before deploying in production
