CVE-2021-39793

Google’s Threat Analysis Group Google states that more than 40% of zero-day flaws discovered in 2022 were variants of previous issues. The popular Threat Analysis Group (TAG) Maddie Stone wrote Google’s fourth annual year-in-review of zero-day flaws exploited in-the-wild [2021, 2020, 2019], it is built off of the mid-year 2022 review. In 2022, the researchers […]

It turns out that the first “all Google” phone includes a non-Google bug. Learn about the details of CVE-2022-38181, a vulnerability in the Arm Mali GPU. Join me on my journey through reporting the vulnerability to the Android security team, and the exploit that used this vulnerability to gain arbitrary kernel code execution and root on a Pixel 6 from an Android app.

In this post I’ll exploit CVE-2022-20186, a vulnerability in the Arm Mali GPU kernel driver and use it to gain arbitrary kernel memory access from an untrusted app on a Pixel 6. This then allows me to gain root and disable SELinux. This vulnerability highlights the strong primitives that an attacker may gain by exploiting errors in the memory management code of GPU drivers.

Google Project Zero states that in H1 2022 at least half of zero-day issues exploited in attacks were related to not properly fixed old flaws. Google Project Zero researcher Maddie Stone published a blog post that resumes her speech at the FIRST conference in June 2022, the presentation is titled “0-day In-the-Wild Exploitation in 2022…so […]

Google Project Zero has observed a total of 18 exploited zero-day vulnerabilities in the first half of 2022, at least half of which exist because previous bugs were not properly addressed.

In this post I’ll exploit CVE-2022-22057, a use-after-free in the Qualcomm gpu kernel driver, to gain root and disable SELinux from the untrusted app sandbox on a Samsung Z flip 3. I’ll look at various mitigations that are implemented on modern Android devices and how they affect the exploit.

The U.S. CISA added the CVE-2022-23176 flaw in WatchGuard Firebox and XTM appliances to its Known Exploited Vulnerabilities Catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the CVE-2022-23176 flaw in WatchGuard Firebox and XTM appliances to its Known Exploited Vulnerabilities Catalog. According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, […]
