CVE-2026-58828: Use After Free

Q: Who is exposed to this issue?

The issue affects Google Android systems using the Android Linux kernel. Exploitation is local, so it is relevant where an attacker can run code on the device.

Q: What does an attacker need to exploit it?

An attacker needs local access to execute code, but no additional execution privileges or user interaction are required. Successful exploitation could result in privilege escalation.

Q: What is the underlying flaw?

The affected base.c functions contain a race condition that can cause a use-after-free condition. This can compromise confidentiality, integrity, and availability.

Published Nov 1, 2026

Updated

In multiple functions of base.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
