PT-2026-40087

Integer overflow in the UEFI firmware for the Slim Bootloader may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable local code execution. This result may potentially occur via local access when attack requirements a...

A UEFI System with SPDM to Protect against Unauthorized Device Connections

Attackers willing to compromise computing systems can use malicious peripherals as an attack vector, threatening users that cannot verify the hardware's authenticity. To address this problem, our work uses the Security Protocol and Data Model to propose a UEFI system capable of authenticating PCI...

CVE-2026-43171

A flaw was found in the Linux kernel's EFI/CPER component. This vulnerability occurs because the cperprintfwerr function does not adequately validate the length of error records against a provided offset. A malicious or malformed firmware could exploit this by providing an offset that causes an...

CVE-2026-43266 EFI/CPER: don't go past the ARM processor CPER record buffer

In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: don't go past the ARM processor CPER record buffer There's a logic inside GHES/CPER to detect if the sectionlength is too small, but it doesn't detect if it is too big. Currently, if the firmware receives an ARM process...
