CVE-2025-62550
Published: 09 December 2025
Description
Out-of-bounds write in Azure Monitor Agent allows an authorized attacker to execute code over a network.
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the out-of-bounds write vulnerability by requiring timely flaw remediation through patching the Azure Monitor Agent as advised by Microsoft.
Implements memory protection mechanisms such as DEP, ASLR, and stack canaries that prevent exploitation of out-of-bounds writes for remote code execution.
Validates network inputs to the Azure Monitor Agent to prevent malformed data from triggering the out-of-bounds write condition.
Security SummaryAI
