{"id":"AZL-66872","summary":"CVE-2025-38711 affecting package kernel for versions less than 6.6.104.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb/server: avoid deadlock when linking with ReplaceIfExists\n\nIf smb2_create_link() is called with ReplaceIfExists set and the name\ndoes exist then a deadlock will happen.\n\nksmbd_vfs_kern_path_locked() will return with success and the parent\ndirectory will be locked.  ksmbd_vfs_remove_file() will then remove the\nfile.  ksmbd_vfs_link() will then be called while the parent is still\nlocked.  It will try to lock the same parent and will deadlock.\n\nThis patch moves the ksmbd_vfs_kern_path_unlock() call to *before*\nksmbd_vfs_link() and then simplifies the code, removing the file_present\nflag variable.","modified":"2026-04-01T05:21:04.284279Z","published":"2025-09-04T16:15:40Z","upstream":["CVE-2025-38711"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38711"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.104.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-66872.json"}}],"schema_version":"1.7.5"}
