That bypasses\nthe normal device lifetime handling and leaks the reference held on the\nembedded struct device.\n\nThe issue was identified by a static analysis tool I developed and\nconfirmed by manual review.\n\nFix this by using put_device() in the host1x_device_parse_dt() failure\npath.\n\n## Affected\n\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < a408d89e20d38d78f540e1951dc4c6056ad662e1`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < 4ee41361c637eafa80f5d88b46d0016e6cdb24db`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < 3642d0a45214e3b4cf61bf5e75b04b490d0b3519`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < edc7267b59a465c6ae7c5ffac2171c30962bd325`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < 4454caa204a2edb19c62754ddb96e5dbca0d2f49`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < c4d6442ac3ed00041fe4e1df715717ed78a7d37f`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < 8559b1501f77a5b5d003790bec170ca449e0c674`\n- `Linux >= f4c5cf88fbd50e4779042268947b2e2f90c20484 < e75717f9aec04355777be41070890c6a815c76df`\n- `Linux 4.0`\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":[]}
