CVE-2026-87765
In the kernel apsys DVFS driver, there is a possible out-of-bounds read or hardware register corruption due to improper input validation of the frequency index. This could lead to system instability or denial of service with local privileges.
CVSS
- Base score
- 5.5
- Version
- 3.1
- Vector
- CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days
- 0.10 %
- Percentile among all scored CVEs
- 1
- Score date
- 10/21/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
ATT&CK techniques
How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.
- Exploitation
T1068Exploitation for Privilege Escalationprivilege escalation85 % - Primary impact
T1499.004Application or System Exploitationimpact80 % - Secondary impact
T1565.001Stored Data Manipulationimpact70 %
AV:L (local), PR:L (requiere privilegios) y A:H (impacto alto en disponibilidad) indican escalada de privilegios local. La corrupción de registros de hardware y lectura fuera de límites provocan DoS e integridad del sistema.
Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
