However, this reference is never\nreleased when the function returns, leading to a dma_buf memory leak.\n\nFix this by adding dma_buf_put before returning from the function,\nensuring that the temporarily acquired reference is properly released\nregardless of whether a matching map is found.\n\nRule: add\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":[]}
