CVE-2021-0945

Estado: ModificadaCrítica (9.8)—

In _PMRCreate of the PowerVR kernel driver, a missing bounds check means it is possible to overwrite heap memory via PhysmemNewRamBackedPMR. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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).
