Report: CVE-2026-31409 - ksmbd: unset conn->binding on failed binding request

CVE ID :CVE-2026-31409 Published : April 6, 2026, 8:16 a.m. | 1 hour, 5 minutes ago Description :In the Linux kernel, the following vulnerability has been resolved: ksmbd: unset conn->binding on failed binding request When a multichannel SMB2_SESSION_SETUP request with SMB2_SESSION_REQ_FLAG_BINDING fails ksmbd sets conn->binding = true but never clears it on the error path. This leaves the connection in a binding state where all subsequent ksmbd_session_lookup_all() calls fall back to the global sessions table. This fix it by clearing conn->binding = false in the error path. Severity: 0.0 | NA Visit the link for more details, such as CVSS details, affected products, timeline, and more...
