{"id":"CVE-2026-99068","summary":"ALSA: ctxfi: Fix memory leakage when clearing DAO input mappers","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: ctxfi: Fix memory leakage when clearing DAO input mappers\n\nCommit e576e7843c0d (\"ALSA: ctxfi: Simplify dao_clear_{left,right}_input() functions\")\ncentralized the DAO input mapper clearing logic in\ndao_clear_input(), but omitted the kfree() calls.\n\nIt removes the mapper entries from the list and sets their pointers\nto NULL without freeing the allocated array. 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.","modified":"2026-10-25T02:47:29.028775445Z","published":"2026-10-23T12:23:11.461Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99068.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0919d8dd19f92e12829055c75fced9a454d644bf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/593d46fc6af9a0178a46e77d6d24b20d2314165f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7dc71c1ce885f5d9f128037ebc75d9c0356e060"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/99xxx/CVE-2026-99068.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99068"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e576e7843c0d65b82d4092e5b386d9fbf5bc10c3"},{"fixed":"f7dc71c1ce885f5d9f128037ebc75d9c0356e060"},{"fixed":"0919d8dd19f92e12829055c75fced9a454d644bf"},{"fixed":"593d46fc6af9a0178a46e77d6d24b20d2314165f"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99068.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.14.0"},{"fixed":"6.18.57"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-99068.json"}}],"schema_version":"1.9.2"}
