If registration fails, input_free_device()\nfrees the input device but data-\u003einput2 still points to the freed memory.\nalps_input_configured() calls hid_hw_open() before allocating input2, so\nURBs are already active and raw_event can fire during the failure window.\nA U1_SP_ABSOLUTE_REPORT_ID report arriving then causes u1_raw_event()\nto dereference the freed data-\u003einput2 -\u003e use-after-free.\n\nFix by only storing input2 into drvdata after successful registration\nand adding a NULL guard in the raw_event path.","modified":"2026-10-19T14:16:49.219875514Z","published":"2026-10-18T16:17:01Z","upstream":["CVE-2026-98501"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98501"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-108752.json"}}],"schema_version":"1.9.0"}
