Vulnerability description
DayBreach CVE AI Research
CVE-2026-93006 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
A flaw was found in dnsmasq. The TFTP server can serve the wrong file contents because a recently used transfer cache is not invalidated when a transfer finishes. An attacker on the local network who can request a TFTP file may cause a later client to receive previously cached data instead of the requested file. In PXE network-boot environments this can substitute attacker-chosen boot content for a victim machine.
