CVE-2026-0076 is a high-severity local privilege escalation vulnerability in Android’s resource parsing engine. The flaw resides in the `validateNode` function of /frameworks/base/libs/androidfw/ResourceTypes.cpp, where an incorrect bounds check during XML resource node validation leads to an out-of-bounds (OOB) read. Specifically, when processing a specially crafted resource table, the function fails to properly verify the `nodeHeader` size against the remaining buffer. This allows an attacker to force the parser to read beyond the allocated memory region, potentially disclosing sensitive kernel or process memory addresses.
The vulnerability is triggered without user interaction, requiring only that a malicious application execute the vulnerable code path. By inducing the OOB read, an attacker can leak critical memory layout information, such as pointers to kernel objects or function addresses. This information can be used to bypass Address Space Layout Randomization (ASLR) and construct a subsequent privilege escalation payload. The flaw affects the Android Framework component, which typically runs with high privileges (system or root). Successful exploitation could lead to full device compromise, including installing persistent backdoors, accessing sensitive user data, and bypassing security policies. Google assigned the CVE on 2026-06-01, and it is expected to be patched in the June 2026 Android Security Bulletin.
DailyCVE Form:
Platform: Android

Vulnerability : OOB read
Severity: High

Prediction: 2026-06-05
What Undercode Say
Check Android build fingerprint adb shell getprop ro.build.fingerprint Find ResourceTypes.cpp location find . -name "ResourceTypes.cpp" -path "/frameworks/base/libs/androidfw/" Check for dangerous bounds check (illustrative) grep -n "if (nodeHeader->size < sizeof(ResXMLParser::NodeHeader))" ResourceTypes.cpp
// Example: Trigger OOB read via malformed resource node
struct MalformedNode {
NodeHeader header;
uint32_t malformed_data[bash]; // Forces read beyond buffer
};
void trigger_oob() {
ResXMLParser parser;
// ... parser initialized with crafted buffer
parser.validateNode((NodeHeader)malformed_node); // OOB read occurs here
}
Exploit
The exploit does not require user interaction. An attacker first crafts a malicious Android application that includes a malformed resource table. When the system parses this resource, `validateNode` incorrectly calculates the buffer boundary, allowing a controlled out-of-bounds read. The attacker then reads adjacent memory pages to leak kernel pointers. Using this information, the attacker bypasses ASLR and executes a return-oriented programming (ROP) chain to escalate privileges to root. The entire attack is local and does not require network access.
Protection
Protect devices by applying the June 2026 Android Security Update as soon as it is available. Until then, disable installation of applications from untrusted sources and restrict execution of unknown code using SELinux in enforcing mode. Enterprises can use Android Enterprise’s managed Google Play to block apps from unknown developers. Additionally, deploy endpoint detection and response (EDR) solutions that monitor for anomalous memory access patterns.
Impact
Successful exploitation results in local privilege escalation, allowing a malicious app to gain `root` or `system` privileges. This can lead to complete device compromise: stealing sensitive data, bypassing security policies, installing persistent malware, and potentially using the compromised device as a pivot point for further attacks within an enterprise network.
