{"id":"AZL-59940","summary":"CVE-2025-21923 affecting package kernel for versions less than 6.6.85.1-2","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nHID: hid-steam: Fix use-after-free when detaching device\n\nWhen a hid-steam device is removed it must clean up the client_hdev used for\nintercepting hidraw access. This can lead to scheduling deferred work to\nreattach the input device. Though the cleanup cancels the deferred work, this\nwas done before the client_hdev itself is cleaned up, so it gets rescheduled.\nThis patch fixes the ordering to make sure the deferred work is properly\ncanceled.","modified":"2026-04-01T05:19:34.674510Z","published":"2025-04-01T16:15:23Z","upstream":["CVE-2025-21923"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-21923"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.85.1-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-59940.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:H/I:H/A:H"}]}
