CVE-2019-11137
HighCVSS 8.2Exploitation Probability (EPSS)
Low risk30th percentile - higher than 30% of all known CVEs
Summary
Insufficient input validation in system firmware for Intel(R) Xeon(R) Scalable Processors, Intel(R) Xeon(R) Processors D Family, Intel(R) Xeon(R) Processors E5 v4 Family, Intel(R) Xeon(R) Processors E7 v4 Family and Intel(R) Atom(R) processor C Series may allow a privileged user to potentially enable escalation of privilege, denial of service and/or information disclosure via local access.
Risk Assessment
A privileged local user could cause a system crash, access sensitive data, or elevate their privileges.
Recommendation
Update the system firmware to the latest version provided by the motherboard/system vendor.
Other vulnerabilities in Intel Xeon Processors
See all- CVE-2026-20901Medium
Some Intel(R) Xeon(R) processors contain an improper input validation vulnerability in firmware that may allow an escalation of privilege. A startup code and SMM adversary with a privileged user and a high complexity attack may enable data alteration. This requires local access but no user interaction. The vulnerability may impact system integrity (high), but not confidentiality or availability.
- CVE-2026-20898High
Improper access control in the firmware for Alias Checking Trusted Module for some Intel(R) Xeon(R) processors may allow privilege escalation. A privileged user with a high complexity attack may enable escalation. This may occur via local access without user interaction. Confidentiality and integrity impact are high.
- CVE-2026-20713Medium
Always-incorrect control flow implementation in Intel Xeon processor firmware may allow privilege escalation. A privileged attacker with a high complexity attack can escalate privileges via local access, without user interaction.
