As soon as complete() is invoked, the\nwaiter (such as iscsit_close_connection()) may wake up and proceed to free\nthe iscsit_conn structure.\n\nIf the waiter frees the memory before the current thread reaches\nspin_unlock_bh(), it results in a KASAN slab-use-after-free as the function\nattempts to release a lock within the already-freed connection structure.\n\nFix this by releasing the spinlock before calling complete().","modified":"2026-08-28T17:47:51.413492515Z","published":"2026-02-18T15:18:42Z","upstream":["CVE-2026-23216"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23216"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-77861.json"}}],"schema_version":"1.9.0"}
