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."}]}],"providerMetadata":{"shortName":"Linux","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","dateUpdated":"2026-08-05T11:39:16.448Z"},"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"5.4.284"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"5.10.226"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"5.15.167"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"6.1.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"6.6.51"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"6.10.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.2","versionEndExcluding":"6.11"}]}]}],"x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-10T13:21:25.873788Z","id":"CVE-2024-47667","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"providerMetadata":{"shortName":"CISA-ADP","orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","dateUpdated":"2024-10-10T13:21:40.905Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"shortName":"CVE","orgId":"af854a3a-2127-422b-91ae-364da2661108","dateUpdated":"2025-11-03T22:20:31.801Z"}}]}}}
