CVE-2026-106026

Estado: AplazadaMedia (6.3)—

tftp-hpa 5.4 before 6.0 contains an out-of-bounds read vulnerability in rewrite_string() in tftpd/remap.c that walks heap memory during jump label searches. Unauthenticated remote attackers can send read or write requests whose filename matches a remap jump rule to crash the forked in.tftpd request handler.

CVSS

Probabilidad de explotación (EPSS)

FIRST aún no ha puntuado esta CVE (habitual en CVEs muy recientes o rechazadas).

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK
