{"id":"DEBIAN-CVE-2024-49874","details":"In the Linux kernel, the following vulnerability has been resolved:  i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition  In the svc_i3c_master_probe function, &master-\u003ehj_work is bound with svc_i3c_master_hj_work, &master-\u003eibi_work is bound with svc_i3c_master_ibi_work. And svc_i3c_master_ibi_work  can start the hj_work, svc_i3c_master_irq_handler can start the ibi_work.  If we remove the module which will call svc_i3c_master_remove to make cleanup, it will free master-\u003ebase through i3c_master_unregister while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows:  CPU0                                         CPU1                                      | svc_i3c_master_hj_work svc_i3c_master_remove               | i3c_master_unregister(&master-\u003ebase)| device_unregister(&master-\u003edev)     | device_release                      | //free master-\u003ebase                 |                                     | i3c_master_do_daa(&master-\u003ebase)                                     | //use master-\u003ebase  Fix it by ensuring that the work is canceled before proceeding with the cleanup in svc_i3c_master_remove.","modified":"2026-09-15T09:02:58.697711446Z","published":"2024-10-21T18:15:08.983Z","upstream":["CVE-2024-49874"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-49874"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.11.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-49874.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.11.4-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-49874.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
