When either of\nthose later steps fails, the core frees its task wrapper and DMA-buffer\nreferences without calling the driver's task_free() callback. Any\ndriver resources allocated by task_create() are therefore leaked.\n\nThe dual-fd allocation path also jumps to cleanup without storing the\nnegative get_unused_fd_flags() result in retval. Since retval still\ncontains the successful task_create() return value, TASK_CREATE can\nincorrectly report success although the task was discarded.\n\nPreserve the fd allocation errors and call task_free() when failure\noccurs after a successful task_create() callback.","state":0,"publishedAt":"2026-07-25T08:51:45.301+00:00","modifiedAt":"2026-10-19T20:48:37.025+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                        \"sound/core/compress_offload.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"04177158cf98a79744937893b100020d77e6f9ac\",\n                            \"lessThan\": \"b27a75d42044d9d4709095617730b91b1c4af423\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"04177158cf98a79744937893b100020d77e6f9ac\",\n                            \"lessThan\": \"426a9947a38d272d0e19c031658da68e31128667\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"04177158cf98a79744937893b100020d77e6f9ac\",\n                            \"lessThan\": \"4a60127debb9e370d6c0e22a307326b624a141f3\",\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                        \"sound/core/compress_offload.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.13\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.13\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.39\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.1.4\",\n                            \"lessThanOrEqual\": \"7.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2\",\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/b27a75d42044d9d4709095617730b91b1c4af423","https://git.kernel.org/stable/c/426a9947a38d272d0e19c031658da68e31128667","https://git.kernel.org/stable/c/4a60127debb9e370d6c0e22a307326b624a141f3"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-64485","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-64485","identifiers":["CVE-2026-64485"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
