resolved:\n\nBluetooth: L2CAP: Fix type confusion in l2cap_ecred_reconf_rsp()\n\nl2cap_ecred_reconf_rsp() casts the incoming data to struct\nl2cap_ecred_conn_rsp (the ECRED *connection* response, 8 bytes with\nresult at offset 6) instead of struct l2cap_ecred_reconf_rsp (2 bytes\nwith result at offset 0).\n\nThis causes two problems:\n\n - The sizeof(*rsp) length check requires 8 bytes instead of the\n correct 2, so valid L2CAP_ECRED_RECONF_RSP packets are rejected\n with -EPROTO.\n\n - rsp->result reads from offset 6 instead of offset 0, returning\n wrong data when the packet is large enough to pass the check.\n\nFix by using the correct type. Also pass the already byte-swapped\nresult variable to BT_DBG instead of the raw __le16 field."}], "lastModified": "2026-06-17T10:48:51.713", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0B1A046E-0C62-426C-8D6D-9BCC6EB56D6E", "versionEndExcluding": "5.10.253", "versionStartIncluding": "5.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "20DDB3E9-AABF-4107-ADB0-5362AA067045", "versionEndExcluding": "5.15.203", "versionStartIncluding": "5.11"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "2EDC6BAF-B710-4E26-B6AA-D68922EE7B43", "versionEndExcluding": "6.1.167", "versionStartIncluding": "5.16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C57BB918-DF28-46B3-94F7-144176841267", "versionEndExcluding": "6.6.130", "versionStartIncluding": "6.2"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "28D591F5-B196-4CC9-905C-DC80F116E7A8", "versionEndExcluding": "6.12.78", "versionStartIncluding": "6.7"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "E5571059-6552-48E7-9BEF-3E358C387171", "versionEndExcluding": "6.18.20", "versionStartIncluding": "6.13"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "96D34333-38BE-4414-9E79-6EB764329581", "versionEndExcluding": "6.19.10", "versionStartIncluding": "6.19"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.0:rc1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F253B622-8837-4245-BCE5-A7BF8FC76A16"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.0:rc2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4AE85AD8-4641-4E7C-A2F4-305E2CD9EE64"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.0:rc3:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F666C8D8-6538-46D4-B318-87610DE64C34"}, {"criteria": "cpe:2.3:o:linux:linux_kernel:7.0:rc4:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "02259FDA-961B-47BC-AE7F-93D7EC6E90C2"}], "operator": "OR"}]}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67"}
