{"id":"AZL-102198","summary":"CVE-2026-93200 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: master: Fix use-after-free of master-\u003ethis\n\nsysfs attribute callbacks for the master controller device dereference\nmaster-\u003ethis.  However, master-\u003ethis is freed in\ni3c_master_detach_free_devs() before the master device itself is\nreleased.\n\nAs a result, sysfs accesses can dereference a freed master-\u003ethis\npointer, leading to a use-after-free.\n\nKeep master-\u003ethis alive until i3c_masterdev_release(), which is called\nafter the master device and its sysfs state are being torn down. Do not\nfree master-\u003ethis as part of the normal device detach path.\n\nOn the error path in i3c_master_set_info(), reset master-\u003ethis and\nbus.cur_master to NULL before freeing the allocated device.","modified":"2026-09-20T05:33:47Z","published":"2026-09-17T17:18:16Z","upstream":["CVE-2026-93200"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93200"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102198.json"}}],"schema_version":"1.9.0"}
