A slave that consumes the skb butreturns an error code (rc < NET_XMIT_MASK, e.g. NET_XMIT_DROP) is treatedas if the skb were still owned, so the loop restores skb->dev and calls__skb_pull() on it. A VLAN slave returns the result of dev_queue_xmit()from its ndo_start_xmit() (propagated since cbbef5e18307), and when thelower qdisc drops the packet that value is NET_XMIT_DROP after the skbhas been freed, giving a use-after-free in teql_master_xmit().\nThe Fix: test for consumption with dev_xmit_complete(), which acceptsNETDEV_TX_OK and every rc < NET_XMIT_MASK, matching other callers thatneed to distinguish consumed results from busy. Only NETDEV_TX_OK keepsthe packet counted in tx_packets/tx_bytes and advances the slave; aconsumed result that is neither a success nor NET_XMIT_CN ends theattempt and is charged to tx_dropped, so lower-qdisc drops are no longerreported as good transmits. NET_XMIT_CN is counted like success becauseit can accompany acceptance of the current packet: pfifo_head_drop dropsthe old head, enqueues the current skb and returns NET_XMIT_CN.\nConditions to recreate the bug:With CONFIG_NET_SCH_TEQL,CONFIG_VLAN_8021Q and CONFIG_DUMMY enabled, add lkrdummy0 (dummy) andlkrvlan0 (VLAN id 37 on lkrdummy0); set a pfifo limit 0 root on lkrdummy0and a teql0 root on lkrvlan0; bring teql0 up with an address and send oneUDP packet to it. The VLAN xmit returns NET_XMIT_DROP from the lowerqdisc while holding a freed skb.\nhttps://www.cve.org/CVERecord?id=CVE-2026-99282https://git.kernel.org/stable/c/fc55d92ae6a4b2e7d062cad6d4c67f6b061d9cdehttps://git.kernel.org/stable/c/2702ae318630787c640ec0d0403ffd9d95c43e9ehttps://git.kernel.org/stable/c/782d6bb8f9b8e9d8591181662222bf74cd3ecf79#kernel #Linux#CVE_2026_99282#bot", "url": "https://infosec.exchange/users/cve/statuses/117575604459568894"}, {"timestamp": "2026-11-07T14:57:58.491Z", "date_only": false, "value": "2026-11-07T14:57:58.491710Z", "kind": "sighting", "label": "Seen", "source": "https://infosec.exchange/users/vuldb/statuses/117575744086433112", "record": "CVE-2026-99282", "field": "creation_timestamp", "uuid": "1b56f5e2-684d-4c73-8e7f-fed646f05b23", "content": "\u26a0\ufe0f A new vulnerability with increased severity was disclosed for Linux Kernel (CVE-2026-99282) https://vuldb.com/vuln/432622", "url": "https://infosec.exchange/users/vuldb/statuses/117575744086433112"}, {"timestamp": "2026-11-07T15:30:28Z", "date_only": false, "value": "2026-11-07T15:30:28Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-HH8X-8F55-7GGP", "record": "GHSA-HH8X-8F55-7GGP", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-07T15:30:29Z", "date_only": false, "value": "2026-11-07T15:30:29Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-HH8X-8F55-7GGP", "record": "GHSA-HH8X-8F55-7GGP", "field": "modified", "linked_record": true}], "metrics": {"as_of": "2026-11-07T19:20:13.211Z", "anchors": {"origin": {"timestamp": "2026-11-07T14:08:47.978Z", "date_only": false, "value": "2026-11-07T14:08:47.978Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-99282", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-07T14:08:47.978Z", "date_only": false, "value": "2026-11-07T14:08:47.978Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-99282", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 18685.233112, "hours": 5.190342531111112, "days": 0.21626427212962965, "min_seconds": 18685.233112, "max_seconds": 18685.233112, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-07T14:08:47.978Z", "date_only": false, "value": "2026-11-07T14:08:47.978Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-99282", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-07T19:20:13.211Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
