CVE-2025-60015

Adjacent authenticated service interruption via out-of-bounds write

Published Oct 15, 2025 · Updated Oct 15, 2025

Out-of-bounds write in affected F5 F5OS-A and F5OS-C releases allows remote authenticated users to corrupt memory from adjacent networks. F5 has not disclosed the affected component, the input that reaches it, or the operation that writes beyond the destination buffer. Low-privileged access and adjacent-network reachability are required; the published impact is limited to loss of availability, with no reported data disclosure or modification.
