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-2026-43210

A flaw was found in the Linux kernel's tracing ring-buffer subsystem. This vulnerability occurs in the rbreaddatabuffer function, which fails to validate the length of an event before using it to determine the next memory address. If an event's length is corrupted, this can lead to an invalid...

CVE-2026-43129

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. When a second-stage kernel is booted via kexec with a memory-limiting command line, the IMA measurement buffer from the previous kernel may fall outside the new kernel's addressable memory. This out-of-bounds...

GHSA-MXQH-Q9H6-V8PQ Nginx-UI: Unauthenticated first-boot instance claim via POST /api/install allows remote bootstrap takeover

Summary An unauthenticated bootstrap takeover exists in nginx-ui during the initial installation window exposed by POST /api/install. When the instance is still uninitialized, POST /api/install is reachable without authentication and accepts attacker-controlled bootstrap data. The handler sets th...

CVE-2025-71285

A flaw was found in the Linux kernel's qrtr driver. A race condition in the Modem Host Interface MHI autoqueue feature for Inter-Processor Communication Router IPCR downlink channels can lead to a NULL pointer dereference. This occurs because a callback function may be invoked before the qrtr...

CVE-2025-54502

A flaw was found in the AMD Platform Configuration Blob APCB SMM driver. A privileged attacker with local access Ring 0 can exploit an incorrect use of a boot service. This vulnerability may allow the attacker to achieve privilege escalation, potentially leading to arbitrary code execution...

CVE-2026-43129

In the Linux kernel, the following vulnerability has been resolved: ima: verify the previous kernel's IMA buffer lies in addressable RAM Patch series "Address page fault in imarestoremeasurementlist", v3. When the second-stage kernel is booted via kexec with a limiting command line such as "mem="...

CVE-2026-43240

CVE-2026-43240 concerns the Linux kernel (x86/kexec) where a second-stage kernel booted with a memory-limiting parameter (mem=…) may place the IMA kexec buffer outside the accessible RAM, causing a kernel panic. The vulnerability arises from a missing range validation for the carried IMA measurem...

CVE-2026-43240 x86/kexec: add a sanity check on previous kernel's ima kexec buffer

In the Linux kernel, the following vulnerability has been resolved: x86/kexec: add a sanity check on previous kernel's ima kexec buffer When the second-stage kernel is booted via kexec with a limiting command line such as "mem=", the physical range that contains the carried over IMA measurement...
