CVE-2025-49492Network attack vector

Memory corruption via out-of-bounds write

Published Jul 1, 2025 · Updated Jul 1, 2025

Out-of-bounds write in ASR Falcon_Linux, Kestrel, and Lapwing_Linux before 1536 allows remote authenticated users to corrupt memory. apps/atcmd_server/src/dev_api.c performs a write that underruns a buffer, but ASR does not disclose the responsible function, input, or bounds calculation. Network access and low privileges are required; ASR does not specify whether exploitation crashes the service or alters data.
