The post-allocation failure\ncases (SRB alloc / qla2x00_start_sp() failure) run with firmware started\nand still send the reject. Apply the same guard to the reject emission\nin qla2xxx_process_purls_pkt().\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":[]}
