CVE-2021-3510

Estado: ModificadaAlta (7.5)—

Zephyr JSON decoder incorrectly decodes array of array. Zephyr versions >= >1.14.0, >= >2.5.0 contain Attempt to Access Child of a Non-structure Pointer (CWE-588). For more information, see https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-289f-7mw3-2qf4

CVSS

Probabilidad de explotación (EPSS)

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).
