    Medium [CVE-2026-53792] Denial of Service via out-of-bounds read with crafted checksum block

    CVE-2026-53792Source published Source updated

    rsync before 3.5.0 contains an out-of-bounds read vulnerability in the sender-side block matching logic that allows a malicious receiver to trigger memory access before the start of an allocated buffer by sending a crafted checksum block with a length of zero. Attackers can send a specially crafted checksum set containing a zero-length block to cause a negative offset calculation during delta computation, resulting in an out-of-bounds read of file data buffer memory on the sender side. A flaw was found in rsync. This can lead to a denial of service on the sender side. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-129. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red…

    Mitigation guidance
    • Disable unused rsyncd services (systemctl disable --now rsyncd), and if actively serving files, restrict port 873 to trusted clients to prevent untrusted pull requests from crashing the daemon. When operating as a client, only push data (rsync src/ host:dst/) to fully trusted receivers, as the out-of-bounds read is triggered by the receiving end.
