{"id":"AZL-69024","summary":"CVE-2025-40084 affecting package kernel for versions less than 6.6.117.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: transport_ipc: validate payload size before reading handle\n\nhandle_response() dereferences the payload as a 4-byte handle without\nverifying that the declared payload size is at least 4 bytes. A malformed\nor truncated message from ksmbd.mountd can lead to a 4-byte read past the\ndeclared payload size. Validate the size before dereferencing.\n\nThis is a minimal fix to guard the initial handle read.","modified":"2026-04-01T05:21:31.736704Z","published":"2025-10-29T14:15:55Z","upstream":["CVE-2025-40084"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-40084"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.117.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-69024.json"}}],"schema_version":"1.7.5"}
