{"id":"CVE-2024-57984","summary":"i3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: dw: Fix use-after-free in dw_i3c_master driver due to race condition\n\nIn dw_i3c_common_probe, &master-\u003ehj_work is bound with\ndw_i3c_hj_work. And dw_i3c_master_irq_handler can call\ndw_i3c_master_irq_handle_ibis function to start the work.\n\nIf we remove the module which will call dw_i3c_common_remove to\nmake cleanup, it will free master-\u003ebase through i3c_master_unregister\nwhile the work mentioned above will be used. The sequence of operations\nthat may lead to a UAF bug is as follows:\n\nCPU0                                      CPU1\n\n                                     | dw_i3c_hj_work\ndw_i3c_common_remove                 |\ni3c_master_unregister(&master-\u003ebase) |\ndevice_unregister(&master-\u003edev)      |\ndevice_release                       |\n//free master-\u003ebase                  |\n                                     | i3c_master_do_daa(&master-\u003ebase)\n                                     | //use master-\u003ebase\n\nFix it by ensuring that the work is canceled before proceeding with\nthe cleanup in dw_i3c_common_remove.","modified":"2026-04-02T12:25:27.052007Z","published":"2025-02-27T02:07:09.373Z","related":["ALSA-2025:20095","USN-7521-2"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/57xxx/CVE-2024-57984.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/60d2fb033a999bb644f8e8606ff4a1b82de36c6f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b0063098fcde17cd2894f2c96459b23388507ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b75439c945b94dd8a2b645355bdb56f948052601"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fc84dd3c909a372c0d130f5f84c404717c17eed8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/57xxx/CVE-2024-57984.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-57984"},{"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":"1dd728f5d4d4b8b53196c1e0fcf86bbaaee39cef"},{"fixed":"60d2fb033a999bb644f8e8606ff4a1b82de36c6f"},{"fixed":"9b0063098fcde17cd2894f2c96459b23388507ca"},{"fixed":"fc84dd3c909a372c0d130f5f84c404717c17eed8"},{"fixed":"b75439c945b94dd8a2b645355bdb56f948052601"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-57984.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"}]}
