CVE-2024-7139

Estado: AplazadaMedia (6.5)—

Due to an unchecked buffer length, a specially crafted L2CAP packet can cause a buffer overflow. This buffer overflow triggers an assert, which results in a temporary denial of service.

If a watchdog timer is not enabled, a hard reset is required to recover the device.

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).
