CVE-2025-63384_CVE-2025-63384

6.5 / 10

MEDIUM

CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Description

A vulnerability was discovered in RISC-V Rocket-Chip v1.6 and before implementation where the SRET (Supervisor-mode Exception Return) instruction fails to correctly transition the processor's privilege level. Instead of downgrading from Machine-mode (M-mode) to Supervisor-mode (S-mode) as specified by the sstatus.SPP bit, the processor incorrectly remains in M-mode, leading to a critical privilege retention vulnerability.
