This would\nlead to a zeroed DMA address being handed out if the agg_idx is\ntranslated to a SW index at a zeroed entry.\n\nFix this by propagating the error out of bnxt_init_nic(). Both callers\nalready check its return value and unwind with bnxt_free_skbs() and\nbnxt_free_mem(), which tolerate a partially initialized RX ring.\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":[]}
