CVE-2023-53723

The CVE-2023-53723 issue is in the Linux kernel’s AMDGPU/SDMA path. The fix prevents disabling the ECC IRQ unconditionally in sdma_v4_0_hw_fini when SDMA ECC is not enabled, which would cause a suspend-cycle warning on some ASICS with SDMA IP v4.0. The root cause is that sdma_v4_0_hw_fini previou...
