But this may\nlead to a UAF because the accessed runtime->dma_area might be freed\nconcurrently, as it's performed outside the PCM ops.\n\nFor avoiding it, move the code into the PCM core and perform it inside\nthe buffer access lock, so that it won't be changed during the\noperation.","state":0,"publishedAt":"2025-06-18T09:33:52.644+00:00","modifiedAt":"2026-10-15T21:52:07.367+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 \"include/sound/pcm.h\",\n \"sound/core/oss/pcm_oss.c\",\n \"sound/core/pcm_native.c\"\n ],\n \"versions\": [\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"c0e05a76fc727929524ef24a19c302e6dd40233f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"8170d8ec4efd0be352c14cb61f374e30fb0c2a25\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"10217da9644ae75cea7330f902c35fc5ba78bbbf\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"f3e14d706ec18faf19f5a6e75060e140fea05d4a\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"74d90875f3d43f3eff0e9861c4701418795d3455\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"bf85e49aaf3a3c5775ea87369ea5f159c2148db4\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"afa56c960fcb4db37f2e3399f28e9402e4e1f470\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"93a81ca0657758b607c3f4ba889ae806be9beb73\",\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 \"include/sound/pcm.h\",\n \"sound/core/oss/pcm_oss.c\",\n \"sound/core/pcm_native.c\"\n ],\n \"versions\": [\n {\n \"version\": \"2.6.12\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"2.6.12\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.4.294\",\n \"lessThanOrEqual\": \"5.4.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.238\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.185\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.141\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.93\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.31\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.14.9\",\n \"lessThanOrEqual\": \"6.14.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.15\",\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/c0e05a76fc727929524ef24a19c302e6dd40233f","https://git.kernel.org/stable/c/8170d8ec4efd0be352c14cb61f374e30fb0c2a25","https://git.kernel.org/stable/c/10217da9644ae75cea7330f902c35fc5ba78bbbf","https://git.kernel.org/stable/c/f3e14d706ec18faf19f5a6e75060e140fea05d4a","https://git.kernel.org/stable/c/74d90875f3d43f3eff0e9861c4701418795d3455","https://git.kernel.org/stable/c/bf85e49aaf3a3c5775ea87369ea5f159c2148db4","https://git.kernel.org/stable/c/afa56c960fcb4db37f2e3399f28e9402e4e1f470","https://git.kernel.org/stable/c/93a81ca0657758b607c3f4ba889ae806be9beb73"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-38078","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-38078","identifiers":["CVE-2025-38078"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
