For SDP VFs this leads to\ninvalid memory access as it was not initialized.\n\nThis patch adds a NULL check for `queue_to_pfc_map` before\ndereferencing it. Also, simplifies the logic by always assigning a\ndefault BPID first, then conditionally overriding it if CONFIG_DCB is\nenabled and the map exists.\n\n## Affected\n\n- `Linux >= 184fb40f731bd3353b0887731f7caba66609e9cd < 59fbbded05e559675930fd521b8d62b72828b52d`\n- `Linux >= 184fb40f731bd3353b0887731f7caba66609e9cd < 056994563935e049093f100efaad7e63ad113814`\n- `Linux 22079d5ae4a33679150f7de89f4107f4e0446886`\n- `Linux >= 6.14.9 < 6.15`\n- `Linux 6.15`\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":[]}
