"HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:L - The defect is in the PCIe root complex's handling of oversized inbound TLPs on AM65x SR 1.0 silicon; it is triggered by DMA traffic to/from an attached endpoint, which a local user drives through ordinary file or network I/O rather than by any remotely-supplied protocol data.\nAC:L - The PCIe-spec default MRRS of 512 bytes is left in place on every downstream device of an unpatched AM654x root complex, so the >2×128-byte AXI burst condition is satisfied by default and repeated large transfers reliably hit the erratum — no race or unattainable state is involved.\nPR:L - No capability check guards the path; any unprivileged local user performing normal I/O against a PCIe-attached storage, network, or wireless device causes the oversized transfers that trigger the payload corruption and hang.\nUI:N - No victim action is required — the oversized transfers occur as a direct result of the attacker's own I/O activity against the PCIe device.\nS:U - The corruption and hang are confined to the SoC's own kernel and its DMA-mapped memory; no separate security authority such as a hypervisor or IOMMU boundary is crossed.\nC:L - The erratum corrupts in-flight TLP payloads within the controller's internal AXI buffers, so residual data from unrelated transactions can be substituted into a buffer the attacker can read back, giving a limited and unpredictable disclosure.\nI:H - The bus silently corrupts arbitrary PCIe payload data crossing between the endpoint and system memory — including kernel driver buffers and DMA-managed structures — and the erratum explicitly notes the corrupt data can destabilize the processor, so integrity loss is serious and uncontrolled.\nA:H - TI documents that the corrupt data can cause associated applications or the processor itself to hang, which is a complete denial of service on the affected system." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus":
