CVE-2025-63384
6.5 · MEDIUMOverview
CVE-2025-63384 is a medium-severity vulnerability affecting chipsalliance rocketchip. It was published on November 10, 2025 and has a CVSS 3.1 base score of 6.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from chipsalliance. Update rocketchip to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
