CVE-2026-23136 affects sparse-read reply handling in the Linux kernel libceph OSD client. Sparse-read progress is tracked by a state machine largely independent of the messenger state. When a connection is lost during a reply payload or the sparse-read state machine returns an error, fault recovery reconnects and retries pending operations without resetting sparse-read state. Consequently, the client can interpret the beginning of a new reply as a continuation of the previous reply, potentially entering an unrecoverable failure loop. The fix resets sparse-read state in osd_fault() before operations are retried.
