CVE-2026-0151 Overview
CVE-2026-0151 is an integer overflow vulnerability in the IntfGraphCreate function of intfgraph.c in Google Android. The integer overflow leads to an out-of-bounds write that attackers can leverage for remote code execution. Exploitation requires no user interaction and no additional execution privileges beyond those already held by the calling context. The flaw is classified under CWE-190: Integer Overflow or Wraparound. Google disclosed the issue in the Android Security Bulletin for June 2026.
Critical Impact
Remote attackers can trigger an out-of-bounds write in IntfGraphCreate to achieve code execution on affected Android devices without user interaction.
Affected Products
- Google Android (per Android Security Bulletin June 2026)
- Devices using the vulnerable intfgraph.c component
- Google Pixel devices receiving the June 2026 security patch level

Technical Details for CVE-2026-0151
Vulnerability Analysis
The vulnerability resides in the IntfGraphCreate routine defined in intfgraph.c. During graph object construction, the function performs arithmetic on size or count inputs without sufficient bounds checking. An integer overflow during this calculation produces an undersized allocation. Subsequent writes into the allocated buffer exceed its true size, yielding an out-of-bounds write condition.
An attacker who supplies crafted input that drives the size calculation to wrap around can corrupt adjacent heap memory. Because the corruption occurs in a system component reachable over the network attack vector, the flaw escalates from memory corruption to remote code execution. Exploitation needs no user interaction, which expands the realistic attack surface to background services that parse attacker-controlled data.
Root Cause
The root cause is unchecked arithmetic on attacker-influenced length or element-count values inside IntfGraphCreate. The product of those values overflows the integer type used for allocation sizing. The allocator returns a buffer smaller than the loop or copy logic expects, and subsequent element writes exceed the allocation boundary [CWE-190].
Attack Vector
The CVSS vector indicates a network-reachable attack surface with low complexity and low privileges required. An attacker delivers crafted data to the vulnerable component, triggering the overflowing allocation path inside IntfGraphCreate. The resulting out-of-bounds write corrupts heap metadata or adjacent objects to achieve control-flow hijack and remote code execution. No verified public proof-of-concept exploit is available at the time of publication.

Detection Methods for CVE-2026-0151
Indicators of Compromise
- Unexpected crashes or SIGSEGV signals in processes that load the intfgraph component
- Abnormal heap corruption traces in tombstoned crash dumps referencing IntfGraphCreate
- Devices running Android security patch levels prior to the June 2026 bulletin
Detection Strategies
- Inventory Android endpoints and compare reported security patch levels against the June 2026 baseline
- Monitor crash telemetry for repeated faults in the intfgraph.c code path, which can indicate exploitation attempts
- Inspect network telemetry for malformed payloads targeting services that invoke graph construction routines
Monitoring Recommendations
- Forward Android device patch-level attestation into the SIEM and alert on devices that remain below the June 2026 patch level
- Correlate native crash reports with network connection metadata to identify probable exploitation attempts
- Track outbound connections from mobile endpoints to unknown command-and-control infrastructure following crash events
How to Mitigate CVE-2026-0151
Immediate Actions Required
- Apply the June 2026 Android security patch level (2026-06-01 or later) to all managed Android devices
- Enforce mobile device management policies that block enrollment of devices missing the current security patch level
- Restrict exposure of vulnerable services on untrusted networks until patches are deployed
Patch Information
Google addressed CVE-2026-0151 in the Android Security Bulletin June 2026. Device manufacturers integrate the upstream fix into their respective monthly security updates. Administrators should validate that managed devices report the 2026-06-01 security patch level or later.
Workarounds
- No vendor-supplied workaround is documented; apply the official patch as the primary remediation
- Limit network exposure of services that invoke the affected component until updates are installed
- Use network segmentation to constrain attacker reach to mobile endpoints pending patch deployment
