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.","state":0,"publishedAt":"2026-10-18T15:48:52.707+00:00","modifiedAt":"2026-10-19T09:25:59.674+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/ethernet/marvell/octeontx2/nic/cn20k.c\",\n                        \"drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.c\",\n                        \"drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"184fb40f731bd3353b0887731f7caba66609e9cd\",\n                            \"lessThan\": \"59fbbded05e559675930fd521b8d62b72828b52d\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"184fb40f731bd3353b0887731f7caba66609e9cd\",\n                            \"lessThan\": \"056994563935e049093f100efaad7e63ad113814\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"22079d5ae4a33679150f7de89f4107f4e0446886\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6.14.9\",\n                            \"lessThan\": \"6.15\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/net/ethernet/marvell/octeontx2/nic/cn20k.c\",\n                        \"drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.c\",\n                        \"drivers/net/ethernet/marvell/octeontx2/nic/otx2_common.h\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.15\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.15\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.10\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/59fbbded05e559675930fd521b8d62b72828b52d","https://git.kernel.org/stable/c/056994563935e049093f100efaad7e63ad113814"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98806","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98806","identifiers":["CVE-2026-98806"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
