The hardware recognizes PTP-over-UDP (ports 319/320, per the V1_L4/V2_L4 filter support), so a routed unicast packet from off-segment reaches the vulnerable code.\nAC:L - The attacker simply emits a PTP packet at the target interface; the hardware sets HNS3_RXD_TS_VLD_B and the NULL deref follows deterministically with no race, no memory-layout dependency, and no victim-side state requirement.\nPR:N - No authentication, credentials, or local account are needed — the packet is processed by the driver before any permission or protocol-level check, and no PTP/hwtstamp configuration must be enabled on the target.\nUI:N - Processing happens automatically in NAPI softirq context on packet receipt; no action by any local user or administrator is required.\nS:U - The NULL dereference panics the kernel within its own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - The fault is a fixed-offset read of `hdev->ptp->flags` at address 0x18 with no attacker-controlled offset and no data returned to the attacker, so no memory contents are disclosed.\nI:N - The bug is a read fault only — no memory is written, no object is freed or reused, and no control-flow or data structure is modified.\nA:H - The NULL pointer dereference occurs in interrupt/softirq context and panics the entire machine (the reported trace ends in crashdump with secondary CPUs failing to stop), and can be re-triggered on every reboot with a single packet." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
