SUSE CVE-2026-45851
In the Linux kernel, the following vulnerability has been resolved: efi: Fix reservation of unaccepted memory table The reserveunaccepted function incorrectly calculates the size of the memblock reservation for the unaccepted memory table. It aligns the size of the table, but fails to account for...

CVE-2026-45851
CVE-2026-45851 concerns a Linux kernel memory management issue in the EFI path. The bug in reserve_unaccepted() miscomputes the memblock reservation size for the unaccepted memory table when the table’s starting address (efi.unaccepted) is not page-aligned. If the table begins partway through a p...

Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: Check the dsbr size from the EFI variable Since the size of the struct btinteldsbr is already known, we can simply start checking there instead of querying the size of the EFI variable. If the final result doe...
Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: ice: fixed NULL access to tx-inuse in iceptptsirq. The E810 device supports a “low latency” firmware interface for accessing and reading Tx timestamps. This interface does not use the standard Tx timestamp logic, due to the laten...
Astra Linux - уязвимость в 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 invoked. According to the UEFI specification, this stack...
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...

Improper initialization in the UEFI firmware for some Intel platforms within Ring 0: Bare Metal OS may allow an information disclosure. System software adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local...
UEFI Reference Firmware Advisory
Summary: A potential security vulnerability in UEFI for some Intel Reference Platforms may allow information disclosure. Intel is releasing firmware updates to mitigate this potential vulnerability. Vulnerability Details: CVEID: CVE-2025-35991 Description: Improper initialization in the UEFI...
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...
