Descriptions
In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/amd: flush any delayed gfxoff on suspend entry"
commit ab4750332dbe ("drm/amdgpu/sdma5.2: add begin/end_use ring
callbacks") caused GFXOFF control to be used more heavily and the
codepath that was removed from commit 0dee72639533 ("drm/amd: flush any
delayed gfxoff on suspend entry") now can be exercised at suspend again.
Users report that by using GNOME to suspend the lockscreen trigger will
cause SDMA traffic and the system can deadlock.
This reverts commit 0dee726395333fea833eaaf838bc80962df886c8.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Revertir "drm/amd: eliminar cualquier gfxoff retrasado al suspender la entrada" commit ab4750332dbe ("drm/amdgpu/sdma5.2: agregar devoluciones de llamada de anillo de inicio/fin de uso") provocó que el control de GFXOFF se utilizará más intensamente y la ruta de código que se eliminó del commit 0dee72639533 ("drm/amd: eliminar cualquier gfxoff retrasado al suspender la entrada") ahora se puede ejercer nuevamente en suspensión. Los usuarios informan que al usar GNOME para suspender el activador de la pantalla de bloqueo provocará tráfico SDMA y el sistema puede bloquearse. Esto revierte el commit 0dee726395333fea833eaaf838bc80962df886c8.
