CVE-2026-52911

The CVE-2026-52911 vulnerability affects the Linux kernel ksmbd code path. When a SESSION_SETUP binds a connection (conn->binding = true), a global session lookup could incorrectly resolve sessions not actually added to the connection’s session list. The fix tightens the global lookup so that ...

CVE-2026-31476

In the Linux kernel, the following vulnerability has been resolved: ksmbd: do not expire session on binding failure When a multichannel session binding request fails e.g. wrong password, the error path unconditionally sets sess-state = SMB2SESSIONEXPIRED. However, during binding, sess points to t...

CVE-2026-31409

In the Linux kernel, the following vulnerability has been resolved: ksmbd: unset conn-binding on failed binding request When a multichannel SMB2SESSIONSETUP request with SMB2SESSIONREQFLAGBINDING fails ksmbd sets conn-binding = true but never clears it on the error path. This leaves the connectio...
