{"id":"CVE-2026-98785","summary":"drm/amd/display: check dc_state_create_copy() for NULL in dm_suspend","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: check dc_state_create_copy() for NULL in dm_suspend\n\ndc_state_create_copy() can return NULL on allocation failure.\ndm_suspend() only conditionally skips dm_gpureset_toggle_interrupts()\nand continues execution, returning success.  dm_resume() then\ndereferences the NULL cached_dc_state in link_enc_cfg_copy() and the\nfollowing dc_state-\u003estream_count loop, crashing during GPU reset\nrecovery.\n\nReturn -ENOMEM immediately if the copy fails, so the caller aborts\nsuspend instead of leaving a NULL cached state for resume.\n\n(cherry picked from commit
