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.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · updated 2026-10-17 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-97572.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":212311,"id":"CVE-2026-97572","ts":1790668147144,"field":"cvss","old":null,"new":"5.5"},{"seq":212310,"id":"CVE-2026-97572","ts":1790668147144,"field":"severity","old":"none","new":"medium"}]}
