CVE-2021-43997

FreeRTOS versions 10.2.0 through 10.4.5 do not prevent non-kernel code from calling the xPortRaisePrivilege internal function to raise privilege. FreeRTOS versions through 10.4.6 do not prevent a third party that has already independently gained the ability to execute injected code to achieve...

CVE-2021-43997

CVE-2021-43997 affects FreeRTOS ARMv7-M and ARMv8-M MPU ports. Versions 10.2.0–10.4.5 allow non‑kernel code to call the internal xPortRaisePrivilege function to raise privilege; versions up to 10.4.6 can enable a second‑stage privilege escalation if injected code branches inside an MPU API wrappe...

CVE-2020-16273

In Arm software implementing the Armv8-M processors all versions, the stack selection mechanism could be influenced by a stack-underflow attack in v8-M TrustZone based processors. An attacker can cause a change to the stack pointer used by the Secure World from a non-secure application if the sta...

Stack overflow

In Arm software implementing the Armv8-M processors all versions, the stack selection mechanism could be influenced by a stack-underflow attack in v8-M TrustZone based processors.

CVE-2020-13844

CVE-2020-13844 relates to Arm Armv8-A core implementations where speculative execution past unconditional changes in control flow can lead to information disclosure via a side-channel (straight-line speculation). The impact is information disclosure with local access; no remote vector is describe...

Design/Logic Flaw

The ARM-based hardware debugging feature on Raspberry Pi 3 module B+ and possibly other devices allows non-secure EL1 code to read/write any EL3 the highest privilege level in ARMv8 memory/register via inter-processor debugging. With a debug host processor A running in non-secure EL1 and a debug...

Lifting the (Hyper) Visor: Bypassing Samsung’s Real-Time Kernel Protection

Posted by Gal Beniamini, Project Zero Traditionally, the operating system’s kernel is the last security boundary standing between an attacker and full control over a target system. As such, additional care must be taken in order to ensure the integrity of the kernel. First, when a system boots, t...

ARM guests may induce host asynchronous abort

ISSUE DESCRIPTION Depending on how the hardware and firmware have been integrated, guest-triggered asynchronous aborts SError on ARMv8 may be received by the hypervisor. The current action is to crash the host. A guest might trigger an asynchronous abort when accessing memory mapped hardware in a...
