{"id":"CVE-2024-56533","summary":"ALSA: usx2y: Use snd_card_free_when_closed() at disconnection","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: usx2y: Use snd_card_free_when_closed() at disconnection\n\nThe USB disconnect callback is supposed to be short and not too-long\nwaiting.  OTOH, the current code uses snd_card_free() at\ndisconnection, but this waits for the close of all used fds, hence it\ncan take long.  It eventually blocks the upper layer USB ioctls, which\nmay trigger a soft lockup.\n\nAn easy workaround is to replace snd_card_free() with\nsnd_card_free_when_closed().  This variant returns immediately while\nthe release of resources is done asynchronously by the card device\nrelease at the last close.","modified":"2026-04-02T12:24:35.351709Z","published":"2024-12-27T14:11:16.256Z","related":["SUSE-SU-2025:0289-1","SUSE-SU-2025:0428-1","SUSE-SU-2025:0499-1","SUSE-SU-2025:0556-1","SUSE-SU-2025:0557-1","SUSE-SU-2025:0565-1","SUSE-SU-2025:0577-1","SUSE-SU-2025:0577-2","SUSE-SU-2025:20165-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20248-1","SUSE-SU-2025:20249-1","USN-7276-1","USN-7277-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56533.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/24fe9f7ca83ec9acf765339054951f5cd9ae5c5d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bd8838c0ea886679a32834fdcacab296d072fbe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/befcca1777525e37c659b4129d8ac7463b07ef67"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dafb28f02be407e07a6f679e922a626592b481b0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e07605d855c4104d981653146a330ea48f6266ed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e869642a77a9b3b98b0ab2c8fec7af4385140909"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ffbfc6c4330fc233698529656798bee44fea96f5"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56533.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56533"},{"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":"230cd5e24853ed4dd960461989b8ed0986d37a99"},{"fixed":"24fe9f7ca83ec9acf765339054951f5cd9ae5c5d"},{"fixed":"befcca1777525e37c659b4129d8ac7463b07ef67"},{"fixed":"7bd8838c0ea886679a32834fdcacab296d072fbe"},{"fixed":"e07605d855c4104d981653146a330ea48f6266ed"},{"fixed":"ffbfc6c4330fc233698529656798bee44fea96f5"},{"fixed":"e869642a77a9b3b98b0ab2c8fec7af4385140909"},{"fixed":"dafb28f02be407e07a6f679e922a626592b481b0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-56533.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
