The bug is in qede TPA completion handling on the NAPI RX fastpath; remote TCP traffic to a Marvell/QLogic FastLinQ NIC causes firmware to post TPA CQEs that are parsed in qede_poll()->qede_rx_int()->qede_rx_process_tpa_cqe()->qede_tpa_cont()/qede_tpa_end().\nAC:L - An attacker can repeatedly send high-rate crafted TCP bursts to maximize TPA aggregation BD counts so all len_list[] slots are non-zero, deterministically hitting the misordered bounds check without races, special memory layout, or victim-specific state.\nPR:N - Only the ability to send Ethernet/TCP packets to a listening host with a qede interface is required; RX and TPA CQE processing occur in softirq before any authentication, capability checks, or local account access.\nUI:N - No victim action is needed beyond normal network operation; packet reception, interrupt handling, and NAPI polling automatically process attacker-supplied frames and completion descriptors.\nS:U - The out-of-bounds read and resulting skb/RX-ring corruption stay within the host kernel security boundary and do not cross VM, container, IOMMU, or sandbox isolation by themselves.\nC:H - The loop reads past len_list[] into adjacent completion-descriptor memory before the bound check, and the same malformed CQE drives qede_fill_frag_skb() with attacker-influenced lengths that can leak uninitialized RX-ring/page data up the network stack.\nI:H - Extra qede_fill_frag_skb() iterations advance frag_id without MAX_SKB_FRAGS limits and consume RX BDs using firmware-supplied lengths, enabling controllable skb shared-info and RX-ring corruption exploitable for arbitrary kernel writes.\nA:H - Corrupted skb fragment metadata and desynchronized RX BD consumption reliably trigger kernel oops/panic or wedged RX processing in softirq, and the condition is remotely repeatable for sustained denial of service."}]}],"providerMetadata":{"dateUpdated":"2026-08-29T06:21:19.318Z","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","shortName":"Linux"},"references":[{"url":"https://git.kernel.org/stable/c/6d203bdd227fca1787f8a80cf84b990936633c5a"},{"url":"https://git.kernel.org/stable/c/bd3a6a083b408e96437dbd86ff543ba9ec3a788b"},{"url":"https://git.kernel.org/stable/c/e30af53dca803893a29eb3bbe0539752ba435410"},{"url":"https://git.kernel.org/stable/c/1aacefd074b5dcc99b8dbcd73e1c963ed5010110"},{"url":"https://git.kernel.org/stable/c/b17751a2ebc4aef3ce6be6f71ee8df92bf5ddfcd"},{"url":"https://git.kernel.org/stable/c/6d46ab395803f162cdc50e8d346e5f1a4e766771"},{"url":"https://git.kernel.org/stable/c/f9ba47fce5932c15891c89c60e76dfaca919cb8d"}],"title":"qede:
