These functions\nuse sizeof(struct v11_compute_mqd) (2048 bytes) instead of sizeof(struct\nv11_sdma_mqd) (512 bytes), causing a 1536-byte overflow.\n\nDuring CRIU checkpoint of an SDMA queue on Navi3x:\n- checkpoint_mqd() reads 2048 bytes from a 512-byte SDMA MQD buffer,\n leaking 1536 bytes of adjacent GTT memory to userspace\n\nDuring CRIU restore:\n- restore_mqd() writes 2048 bytes into a 512-byte SDMA MQD buffer,\n corrupting 1536 bytes of adjacent GTT memory (often the ring buffer\n or neighboring MQDs)\n\nThis is a copy-paste regression unique to v11. All other ASIC backends\n(cik, vi, v9, v10, v12) correctly use the SDMA-specific variants.\n\nAdd checkpoint_mqd_sdma() and restore_mqd_sdma() functions that properly\nhandle the smaller v11_sdma_mqd structure, matching the pattern used in\nother MQD managers.\n\n(cherry picked from commit 6fa41db7ffdec97d62433adf03b7b9b759af8c2c)"}], "lastModified": "2026-06-30T14:44:27.313", "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
