Ideally we would also want to signal that the IRQ\nthread no longer needs to be run after the timeout is hit to avoid the\nextra check for a valid transfer.","state":0,"publishedAt":"2025-12-24T12:09:42.213+00:00","modifiedAt":"2026-10-16T15:09:44.157+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/spi/spi-tegra210-quad.c\"\n ],\n \"versions\": [\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"88db8bb7ed1bb474618acdf05ebd4f0758d244e2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"83309dd551cfd60a5a1a98d9cab19f435b44d46d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"c934e40246da2c5726d14e94719c514e30840df8\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"551060efb156c50fe33799038ba8145418cfdeef\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"bb0c58be84f907285af45657c1d4847b960a12bf\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"01bbf25c767219b14c3235bfa85906b8d2cb8fbc\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"921fc1838fb036f690b8ba52e6a6d3644b475cbb\",\n \"lessThan\": \"b4e002d8a7cee3b1d70efad0e222567f92a73000\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\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/spi/spi-tegra210-quad.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.12\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.12\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.198\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.160\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.120\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.63\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.17.13\",\n \"lessThanOrEqual\": \"6.17.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.2\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.19\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/88db8bb7ed1bb474618acdf05ebd4f0758d244e2","https://git.kernel.org/stable/c/83309dd551cfd60a5a1a98d9cab19f435b44d46d","https://git.kernel.org/stable/c/c934e40246da2c5726d14e94719c514e30840df8","https://git.kernel.org/stable/c/551060efb156c50fe33799038ba8145418cfdeef","https://git.kernel.org/stable/c/bb0c58be84f907285af45657c1d4847b960a12bf","https://git.kernel.org/stable/c/01bbf25c767219b14c3235bfa85906b8d2cb8fbc","https://git.kernel.org/stable/c/b4e002d8a7cee3b1d70efad0e222567f92a73000"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-68746","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-68746","identifiers":["CVE-2025-68746"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
