The DMA API requires that\nthe dma cookie passed to dma_unmap_single() is the same as the value\nreturned from dma_map_single(). However, by moving the assignment\nlater, this is not the case when priv->dma_cap.addr64 > 32 as \"des\"\nis offset by proto_hdr_len.\n\nThis causes problems such as:\n\n dwc-eth-dwmac 2490000.ethernet eth0: Tx DMA map failed\n\nand with DMA_API_DEBUG enabled:\n\n DMA-API: dwc-eth-dwmac 2490000.ethernet: device driver tries to +free DMA memory it has not allocated [device address=0x000000ffffcf65c0] [size=66 bytes]\n\nFix this by maintaining \"des\" as the original DMA cookie, and use\ntso_des to pass the offset DMA cookie to stmmac_tso_allocator().\n\nFull details of the crashes can be found at:\nhttps://lore.kernel.org/all/d8112193-0386-4e14-b516-37c2d838171a@nvidia.com/\nhttps://lore.kernel.org/all/klkzp5yn5kq5efgtrow6wbvnc46bcqfxs65nz3qy77ujr5turc@bwwhelz2l4dw/","state":0,"publishedAt":"2024-12-29T08:48:51.495+00:00","modifiedAt":"2026-10-15T01:00:13.603+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/stmicro/stmmac/stmmac_main.c\"\n ],\n \"versions\": [\n {\n \"version\": \"ece593fc9c00741b682869d3f3dc584d37b7c9df\",\n \"lessThan\": \"05968b6dd0ffc65d7386608b11a11fb4fdfc9f36\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"a3ff23f7c3f0e13f718900803e090fd3997d6bc9\",\n \"lessThan\": \"6abcdc9a73274052a9e96a1926994ecf9aedad82\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"07c9c26e37542486e34d767505e842f48f29c3f6\",\n \"lessThan\": \"db3667c9bbfbbf5de98e6c9542f7e03fb5243286\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"66600fac7a984dea4ae095411f644770b2561ede\",\n \"lessThan\": \"9d5dd7ccea1b46a9a7c6b3c2b9e5ed8864e185e2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"66600fac7a984dea4ae095411f644770b2561ede\",\n \"lessThan\": \"4c49f38e20a57f8abaebdf95b369295b153d1f8e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"58d23d835eb498336716cca55b5714191a309286\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5.15.171\",\n \"lessThan\": \"5.15.209\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.116\",\n \"lessThan\": \"6.1.167\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.60\",\n \"lessThan\": \"6.6.68\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.11.7\",\n \"lessThan\": \"6.12\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"drivers/net/ethernet/stmicro/stmmac/stmmac_main.c\"\n ],\n \"versions\": [\n {\n \"version\": \"6.12\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"6.12\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.209\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.167\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.68\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.7\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.13\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":10,"severity":"CRITICAL"}],"references":["https://git.kernel.org/stable/c/05968b6dd0ffc65d7386608b11a11fb4fdfc9f36","https://git.kernel.org/stable/c/6abcdc9a73274052a9e96a1926994ecf9aedad82","https://git.kernel.org/stable/c/db3667c9bbfbbf5de98e6c9542f7e03fb5243286","https://git.kernel.org/stable/c/9d5dd7ccea1b46a9a7c6b3c2b9e5ed8864e185e2","https://git.kernel.org/stable/c/4c49f38e20a57f8abaebdf95b369295b153d1f8e"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-56719","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-56719","identifiers":["CVE-2024-56719"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
