CVE-2026-67846: n/a
CVE-2026-67846 is a high-severity vulnerability in the Berkeley Out-of-Order Machine (BOOM) affecting the v3 and v4 NBDTLB implementations. It involves a potential incorrect privilege assignment due to the use of the raw mstatus.SUM value in permission logic without validating the local satp.MODE. This flaw could lead to unauthorized read and write access. No specific affected versions or patches are provided in the available data.
AI Analysis
Technical Summary
The vulnerability CVE-2026-67846 exists in BOOM commit 5223e44cfeb26f41380057a2eb4d651197475f69, specifically in the v3 and v4 NBDTLB implementations. The issue arises because the raw mstatus.SUM bit is used in the read and write permission logic without an explicit check of the local satp.MODE validity at the point of use. This can result in incorrect privilege assignments, potentially allowing unauthorized access to memory operations.
Potential Impact
This vulnerability has a CVSS score of 7.8 (high severity) with impact on confidentiality, integrity, and availability (all rated high). It could allow an attacker with limited privileges (local access with low complexity) to gain unauthorized read and write permissions, potentially compromising system security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, review privilege assignment logic and consider additional access controls or monitoring as interim measures.
