CVE-2026-23163

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix NULL pointer dereference in amdgpu_gmc_filter_faults_remove On APUs such as Raven and Renoir (GC 9.1.0, 9.2.2, 9.3.0), the ih1 and ih2 interrupt ring buffers are not initialized. This is by design, as these secondary IH rings are only available on discrete GPUs. See vega10_ih_sw_init() which explicitly skips ih1/ih2 initialization when AMD_IS_APU is set. However, amdgpu_gmc_filter_faults_remove() unconditional
