Thus, set_queue_properties_from_criu() is not\nfilling out the buffer fields of queue_properties, which\ncan come up when subsequent code expects them to be non-null.\n\nAdd the proper call to kfd_queue_acquire_buffers(), and also\nuse the right cast types in set_queue_properties_from_criu()\n(which were missed at the same time)\n\n(cherry picked from commit 88ed96abbbe27b70193544fbc1ee06448c274714)\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < e2dbdd14c3352483a89e4a9afda05d0f3fcc2c83`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < c6c290e408fe328e091f0bf7502a42b0deea82e9`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 20a5e7ffdfecddc34c60a6b4483f42acf3d8731d`\n- `Linux < 6.12.111`\n- `Linux < 6.18.53`\n- `Linux (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
