{"id":"AZL-102269","summary":"CVE-2026-90180 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nblock: mtip32xx: synchronize ioctls with device removal\n\nThe ioctl handlers only test REMOVE_PENDING before entering\nmtip_hw_ioctl(). Removal can set that bit immediately afterwards and free\ndd-\u003eport in mtip_hw_exit() while an ioctl still dereferences it. An already\nopen block device can reach the handlers while del_gendisk() is in\nprogress.\n\nSerialize both native and compat ioctls with removal. Set REMOVE_PENDING\nbefore taking the mutex so new callers fail after an in-flight ioctl has\ndrained, and hold the mutex until the port has been torn down.","modified":"2026-09-21T05:34:22Z","published":"2026-09-17T17:17:12Z","upstream":["CVE-2026-90180"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90180"}],"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-102269.json"}}],"schema_version":"1.9.0"}
