This leaks memory each\ntime dao_clear_input() is called.\n\nStore the base pointer of the allocation before clearing the mapper\nentries and free the array after removing entries from the list.","state":0,"publishedAt":"2026-10-23T12:23:11.461+00:00","modifiedAt":"2026-10-23T12:23:11.461+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/pci/ctxfi/ctdaio.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"e576e7843c0d65b82d4092e5b386d9fbf5bc10c3\",\n                            \"lessThan\": \"f7dc71c1ce885f5d9f128037ebc75d9c0356e060\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"e576e7843c0d65b82d4092e5b386d9fbf5bc10c3\",\n                            \"lessThan\": \"0919d8dd19f92e12829055c75fced9a454d644bf\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"e576e7843c0d65b82d4092e5b386d9fbf5bc10c3\",\n                            \"lessThan\": \"593d46fc6af9a0178a46e77d6d24b20d2314165f\",\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/pci/ctxfi/ctdaio.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.14\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.57\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.11\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/f7dc71c1ce885f5d9f128037ebc75d9c0356e060","https://git.kernel.org/stable/c/0919d8dd19f92e12829055c75fced9a454d644bf","https://git.kernel.org/stable/c/593d46fc6af9a0178a46e77d6d24b20d2314165f"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-99068","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-99068","identifiers":["CVE-2026-99068"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
