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"}],"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"}}]}}
