CVE-2026-25194 Memory corruption in 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.
A privileged local attacker can cause a denial of service in Intel Slim Bootloader via an out-of-bounds write vulnerability.

What is CVE-2026-25194?
CVE-2026-25194 is a low-severity memory corruption vulnerability in 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., published on 11 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Out-of-bounds write in the firmware for the Intel(R) Slim Bootloader may allow a denial of service.
