Integer overflow in the UEFI firmware for the Intel(R) Slim Bootloader may allow an information disclosure. System software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (low), integrity (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (low), integrity (none) and availability (low) impacts.
AI Analysis
Technical Summary
This vulnerability involves an integer overflow in the Intel Slim Bootloader's UEFI firmware. An authenticated adversary with local access can exploit this flaw with low complexity and active user interaction to cause information disclosure and denial of service. The attack does not require special internal knowledge and does not affect system integrity. The CVSS 4.0 base score is 2.4, reflecting low confidentiality and availability impacts. No vendor advisory or patch information is provided at this time.
Potential Impact
The vulnerability may lead to low-impact information disclosure and denial of service on affected systems. Integrity is not affected. Exploitation requires local authenticated access and user interaction, limiting the scope and severity of the impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or mitigation is currently documented. Until a patch is available, restrict local authenticated access and monitor for suspicious activity related to the Slim Bootloader.
