Now things will go\nhorribly wrong, DMA is going to access a unmapped/unreferenced memory\nregion, corrupted data will be transmited or iommu fault will be\ntriggered :(\n\nIn contrast, the for-loop that maps SKB fragments behaves perfectly\nas expected, and that is how the driver should do for both non-paged\ndata and paged frags actually.\n\nThis patch corrects DMA map/unmap sequences by fixing the array index\nfor tx_q->tx_skbuff_dma[entry].buf when assigning DMA buffer address.\n\nTested and verified on DWXGMAC CORE 3.20a" } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H", "baseScore": 9.4, "baseSeverity": "CRITICAL" }, "scenarios": [ { "lang": "en", "value": "AV:N - The vulnerable code is the stmmac TSO transmit path, driven directly by remote traffic — an unauthenticated peer pulling data from any service on the device, or forwarded/GRO-coalesced streams re-segmented on egress by an stmmac-based gateway, arm the bug, and the resulting corrupted frames (carrying recycled kernel memory) are delivered to that remote peer. The attacker set is not bounded to the local LAN or local machine.\nAC:L - On the common 40/48-bit AXI platforms the mismatched map/unmap occurs on essentially every TSO frame whose linear head carries payload, in the default configuration, and the attacker can drive that path at line rate without limit, so the DMA-completion window is hit repeatedly rather than requiring a skilled one-shot race win.\nPR:N - No authentication or privilege is needed — merely causing the host to transmit large TCP/UDP-GSO data (a plain TCP connection to any listening service, or traffic routed through the device) reaches the code; locally, an ordinary unprivileged socket send suffices.\nUI:N - Triggering requires only network traffic to or through the affected interface; no action by any local user or administrator is involved.\nS:U - The stale IOVA is recycled within the same device's own DMA domain and the impacted resources belong to the kernel that owns the driver, so no security authority boundary (VM, IOMMU domain, sandbox) is crossed.\nC:H - When the unmapped IOVA or SWIOTLB slot is reused before the engine finishes, the MAC reads whatever buffer now occupies it — other sockets' packet data, page-pool/page-frag pages, or another device's bounced I/O — and transmits it on the wire with valid hardware checksums, handing an unbounded amount of kernel memory straight to the remote peer.\nI:L - Outbound frame contents are silently replaced with unrelated memory and re-checksummed by hardware, so peers accept corrupted data undetected, but the device only performs DMA reads — there is no kernel write primitive and the attacker cannot control what gets corrupted.\nA:H - DMA to a torn-down mapping raises IOMMU translation faults and aborted transactions, producing TX errors, log floods, TX-watchdog-driven device resets and link loss, and on SoCs that escalate the resulting bus error an unrecoverable external abort." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/ethernet/stmicro/stmmac/stmmac_main.c" ], "versions": [ { "version": "f748be531d7012c456b97f66091d86b3675c5fef", "lessThan": "ece593fc9c00741b682869d3f3dc584d37b7c9df", "status": "affected", "versionType": "git" }, { "version": "f748be531d7012c456b97f66091d86b3675c5fef", "lessThan": "a3ff23f7c3f0e13f718900803e090fd3997d6bc9", "status": "affected", "versionType": "git" }, { "version": "f748be531d7012c456b97f66091d86b3675c5fef", "lessThan": "07c9c26e37542486e34d767505e842f48f29c3f6", "status": "affected", "versionType": "git" }, { "version": "f748be531d7012c456b97f66091d86b3675c5fef", "lessThan": "58d23d835eb498336716cca55b5714191a309286", "status": "affected", "versionType": "git" }, { "version": "f748be531d7012c456b97f66091d86b3675c5fef", "lessThan": "66600fac7a984dea4ae095411f644770b2561ede", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/ethernet/stmicro/stmmac/stmmac_main.c" ], "versions": [ { "version": "4.7", "status": "affected" }, { "version": "0", "lessThan": "4.7", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.171", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.116", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.60", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.7", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ] } ], "cpeApplicability": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.7", "versionEndExcluding": "5.15.171" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.7", "versionEndExcluding": "6.1.116" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.7", "versionEndExcluding": "6.6.60" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.7", "versionEndExcluding": "6.11.7" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.7", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/ece593fc9c00741b682869d3f3dc584d37b7c9df" }, { "url": "https://git.kernel.org/stable/c/a3ff23f7c3f0e13f718900803e090fd3997d6bc9" }, { "url": "https://git.kernel.org/stable/c/07c9c26e37542486e34d767505e842f48f29c3f6" }, { "url": "https://git.kernel.org/stable/c/58d23d835eb498336716cca55b5714191a309286" }, { "url": "https://git.kernel.org/stable/c/66600fac7a984dea4ae095411f644770b2561ede" } ], "title": "net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB data", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2024-53058", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:12:56.492428Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "description": "CWE-noinfo Not enough information" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:17:17.845Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:28:51.972Z" } } ] } }
