CVE-2024-11263

Estado: AnalizadaAlta (8.4)—

When the Global Pointer (GP) relative addressing is enabled (CONFIG_RISCV_GP=y), the gp reg points at 0x800 bytes past the start of the .sdata section which is then used by the linker to relax accesses to global symbols.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L, PR:N, UI:N indica acceso local sin interacción (T1068). GP relocation abuse en RISC-V permite ejecutar código arbitrario y escalar privilegios modificando referencias globales. Zephyr es RTOS embebido.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
