    "summary": "In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but released in gfx_v9_0_hw_fini(), so the put site has to query amdgpu_irq_enabled() because the get is skipped on SR-IOV VF. ras_late_init / ras_fini have no suspend counterpart, so move the put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a matching ras_suspend callback that is invoked from amdgpu_ras_suspend() before disable_all_features(). The get and put now sit in the same place and check the same condition (not VF, funcs registered), no refcount querying needed. An active flag gates ras_fini so the suspend-then-unload-without-resume path falls into amdgpu_ras_block_late_fini_default() instead of double-releasing what ras_suspend already cleaned up. Drop the cp_ecc_error_irq put from gfx_v9_0_hw_fini(). gfx_v8_0 manages cp_ecc_error_irq locally and is unaffected; no other GFX generation has this IRQ.",
