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