CVE-2025-35968
Protection mechanism failure in the UEFI firmware for the Slim Bootloader within firmware may...
Protection mechanism failure in the UEFI firmware for the Slim Bootloader within firmware may allow an escalation of privilege. Startup code and smm adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. 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 (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
