    CVE-2026-62653

    A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). The input received over a proprietary communication protocol that is exposed when the device is placed into a special firmware-update mode is not properly validated, resulting in a memory corruption condition. This could allow an unauthenticated attacker with physical access to the device to cause a crash and potentially execute arbitrary code on the device.
