CVE-2023-21010 : What You Need to Know

This is a detailed overview of CVE-2023-21010, a recently published vulnerability affecting Android systems.

Understanding CVE-2023-21010

CVE-2023-21010 is a security vulnerability found in multiple locations of the p2p_iface.cpp file in the Android operating system. The vulnerability could potentially result in an out-of-bounds read due to a missing bounds check. Exploitation of this vulnerability could lead to local information disclosure, requiring system execution privileges but not user interaction for exploitation.

What is CVE-2023-21010?

The CVE-2023-21010 vulnerability is classified as an information disclosure type of vulnerability. It poses a risk of leaking sensitive local information due to the absence of proper bounds checking in certain areas of the code.

The Impact of CVE-2023-21010

If successfully exploited, this vulnerability could allow an attacker to gain access to sensitive information stored on an affected Android device. This information disclosure could potentially compromise user privacy and security.

Technical Details of CVE-2023-21010

The following technical details provide insight into the specific aspects of the CVE-2023-21010 vulnerability:

Vulnerability Description

The vulnerability stems from a lack of proper bounds checking in the p2p_iface.cpp file within the Android operating system. This oversight can result in unauthorized access to memory locations outside the defined boundaries, leading to potential information disclosure.
