Vulnerability description

DayBreach CVE AI Research

CVE-2026-79625 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacker with monitoring access can exploit this issue to cause incorrect data processing or a denial-of-service condition.
