When an allocation fails, the previously\nsuccessful allocations are not freed on exit.\n\nFix that by jumping to err_free_rings label on error, which calls\nrtl8180_free_rx_ring() to free the allocations. Remove the free of\nrx_ring in rtl8180_init_rx_ring() error path, and set the freed\npriv->rx_buf entry to null, to avoid double free.\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":[]}
