When some error occurs,\nstream_info-\u003estream_ctx_array is not released, which will lead to a\nmemory leak.\n\nWe can fix it by releasing the stream_info-\u003estream_ctx_array with\nxhci_free_stream_ctx() on the error path to avoid the potential memory\nleak.","modified":"2026-03-20T12:22:35.840391Z","published":"2025-10-07T15:21:08.629Z","related":["SUSE-SU-2025:4111-1","SUSE-SU-2025:4135-1","SUSE-SU-2025:4139-1","SUSE-SU-2025:4149-1","SUSE-SU-2025:4188-1","SUSE-SU-2025:4189-1","SUSE-SU-2025:4320-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50544.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/782c873f8e7686f5b3c47e8b099f7e08c3dd1fdc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e271f42a5cc3768cd2622b929ba66859ae21f97"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7fc6bab3413e6a42bb1264ff7c9149808c93a4c7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91271a3e772e180bbb8afb114c72fd294a02f93d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9fa81cbd2dd300aa8fe9bac70e068b9a11cbb144"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a40ad475236022f3432880e3091c380e46e71a71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ddab9fe76296840aad686c66888a9c1dfdbff5ff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e702de2f5c893bf2cdb0152191f99a6ad1411823"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fcd594da0b5955119d9707e4e0a8d0fb1c969101"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50544.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50544"},{"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":"8df75f42f8e67e2851cdcf6da91640fb881defd1"},{"fixed":"7fc6bab3413e6a42bb1264ff7c9149808c93a4c7"},{"fixed":"e702de2f5c893bf2cdb0152191f99a6ad1411823"},{"fixed":"ddab9fe76296840aad686c66888a9c1dfdbff5ff"},{"fixed":"9fa81cbd2dd300aa8fe9bac70e068b9a11cbb144"},{"fixed":"91271a3e772e180bbb8afb114c72fd294a02f93d"},{"fixed":"fcd594da0b5955119d9707e4e0a8d0fb1c969101"},{"fixed":"a40ad475236022f3432880e3091c380e46e71a71"},{"fixed":"782c873f8e7686f5b3c47e8b099f7e08c3dd1fdc"},{"fixed":"7e271f42a5cc3768cd2622b929ba66859ae21f97"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-50544.json"}}],"schema_version":"1.7.5"}
