As part of our findings, we have identified several bootloader vulnerabilities in Huawei Kirin chipsets. In addition to that publication, we have also recently disclosed an additional bootrom vulnerability (CVE-2021-22429) in Huawei Kirins. As it has been publicized, many of these bootload

In previous posts, we have shown that the Neural Networking features of modern Android devices can lead to serious - if quite traditional - vulnerabilities. This time, we present a vulnerability in which Machine Learning is not the culprit - but the tool we

First reported Apr 11, 2020 11:15 UTCCatalog metadata updated Oct 08, 2026 03:51 UTCOpen evidence recordSummary In a previous advisory we disclosed multiple vulnerabilities within the NPU device’s mmap handler and discussed how it exposes sensitive kernel data. This advisory focuses on the implementation errors in the same handler. The mapping function ignores the requested size parameter and fails to back regions of the mapped virtual memory with an actual mapping. Trying to access these holes or r

These bugs can be abused by various privileged processes to cause NULL pointer accesses and crash the kernel. Vulnerability Details The kernel uses the dma_buf_vmap function if it needs to map a dma buffer into the kernel address space to access its content. Th

Fields of the structure are written with user provided values. A malicious actor can use this vulnerability to overwrite kernel memory with controlled data. The mmap handler is exposed through the /dev/davinci0 character device. Due to the a

While I was working on completing my proof of concept exploit, Ben Hawkes from Google’s Project Zero reported the same vulnerabilities to Samsung. Later that year Brandon Azad released an article documenting his approach of turning these bugs into an arbitrary kernel code execut
First reported Jun 08, 2021 00:00 UTCCatalog metadata updated Oct 08, 2026 03:51 UTCOpen evidence recordSummary The NPU device’s kernel driver implements a custom mmap handler that exposes trusted kernel data to user space. These exposed structures contain sensitive data, including kernel pointers, which can be controlled by a user process. The content of these structures is inherently trusted by the kernel, the pointers are accessed for reading and writing at various places. This provides a very co

The exploitability of the vulnerability depends on how the various kernel drivers use the allocated ION buffers, the version of the kernel and the vendor specific modifications to the ION subsystem. In the most serious cases th
