Fix this\nby initializing the completion before the ib_copy_to_udata call.\n\n## Affected\n\n- `Linux >= b48c24c2d710cf34810c555dcef883a3d35a9c08 < ac1da7bd224d406b6f1b84414f0f652ab43b6bd8`\n- `Linux >= b48c24c2d710cf34810c555dcef883a3d35a9c08 < af310407f79d5816fc0ab3638e1588b6193316dd`\n- `Linux >= b48c24c2d710cf34810c555dcef883a3d35a9c08 < cd1534c8f4984432382c240f6784408497f5bb0a`\n- `Linux >= b48c24c2d710cf34810c555dcef883a3d35a9c08 < 3cb88c12461b71c7d9c604aa2e6a9a477ecfa147`\n- `Linux >= b48c24c2d710cf34810c555dcef883a3d35a9c08 < f72996834f7bdefc2b95e3eec30447ee195df44e`\n- `Linux >= b48c24c2d710cf34810c555dcef883a3d35a9c08 < 11a95521fb93c91e2d4ef9d53dc80ef0a755549b`\n- `Linux 5.14`\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":[]}
