Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/efistub: Calls boot services in mixed mode on the firmware’s stack Normally, the EFI stub calls into EFI boot services using the stack that was active when the stub was entered. According to the UEFI specification, this stack...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: x86/ioremap: Maps EFI-reserved memory as encrypted for SEV. Some drivers require memory that is marked as EFI boot services data. To prevent this memory from being reused by the kernel after ExitBootServices, efimemreserve is use...

SUSE CVE-2019-12380

DISPUTED An issue was discovered in the efi subsystem in the Linux kernel through 5.1.5. physefisetvirtualaddressmap in arch/x86/platform/efi/efi.c and eficallphysprolog in arch/x86/platform/efi/efi64.c mishandle memory allocation failures. NOTE: This id is disputed as not being an issue because...

EUVD-2026-29524

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...

CVE-2025-35991

The CVE-2025-35991 entry describes an improper initialization in the UEFI firmware for some Intel platforms (Ring 0: Bare Metal OS) that may allow information disclosure. The issue requires a local attacker with privileged access and high attack complexity, with no user interaction, and could imp...

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...

CVE-2026-6862

A flaw was found in libefiboot, a component of efivar. The device path node parser in libefiboot fails to validate that each node's Length field is at least 4 bytes, which is the minimum size for an EFI Extensible Firmware Interface device path node header. A local user could exploit this...
