A later core probe can therefore see\na non-NULL rdev, skip rocket_device_init(), and dereference the error\npointer when reading rdev->num_cores.\n\nSave the error code and clear rdev before returning from the\nrocket_device_init() failure path.\n\n## Affected\n\n- `Linux >= ed98261b41687323ffa02ca20fef1e60b38fd1aa < 79071b67182e1b352d51a3917729b8d424710b49`\n- `Linux >= ed98261b41687323ffa02ca20fef1e60b38fd1aa < dd47a6c920083b069f00f0920e4566915a6aec46`\n- `Linux >= ed98261b41687323ffa02ca20fef1e60b38fd1aa < 4ac852419f0d317c7bd8db5b8acb3cc78be7fe33`\n- `Linux 6.18`\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":[]}
