CVE-2026-25194

LOWCVSS 1.8/10

Last modified

CVE-2026-25194 is a low-severity vulnerability rated 1.8/10 on the CVSS scale. Out-of-bounds write in the firmware for the Intel(R) Slim Bootloader may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable denial of service.

Description

Out-of-bounds write in the firmware for the Intel(R) Slim Bootloader may allow a denial of service. System software adversary with a privileged user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
