2 techniques across 2 tactics: Execution, Privilege Escalation

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Exploitation requires the vulnerable code path in PduParser.java to process an attacker-supplied PDU (Protocol Data Unit, as used in Android MMS/messaging parsing); the attacker must be able to deliver a crafted/malformed PDU to the device. No user interaction is required (UI:N) and no additional execution privileges are stated as needed per the description. The CVSS vector lists PR:L, implying some privilege may be required, which conflicts with the 'no additional execution privileges needed' description - this limiting factor is unverified. Impact is confined to denial of service (availability); there is no confidentiality or integrity impact, and no code execution. Exploitation is rated non-automatable by SSVC. Affected to Android 14, 15, 16, 16-qpr2, and 17.

Impact

This is a moderate, low-priority issue despite its CVSS 6.5 (MEDIUM) rating, and multiple independent signals agree on that. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) scopes impact to availability only (C:N/I:N) - an out-of-bounds read (CWE-119) causing a remote denial of service, not code execution. CISA's SSVC framework reinforces low urgency: Exploitation=none (no observed or public exploitation), Automatable=no, and Technical Impact=partial. EPSS and KEV are not present in the input; absence of a KEV listing is consistent with SSVC Exploitation=none, indicating no evidence of active exploitation. There is a notable internal conflict in the authentication signal that defenders should verify: the CVSS vector specifies PR:L (some privileges required), yet the Android description states the flaw 'could lead to a remote denial of service with no additional execution privileges needed' and 'User interaction is not needed' - the 'no additional privileges' wording reads closer to PR:N. This discrepancy should be verified against the Android bulletin before relying on PR:L as a mitigating factor. Also note A:H in the vector versus SSVC Technical Impact=partial, suggesting the real-world availability impact (a parser crash) is likely a bounded component DoS rather than total device unavailability.

Exploit ScenarioDerived

An attacker delivers a malformed PDU (e.g., a crafted MMS/messaging payload) to a target Android device; when PduParser.java parses it, the missing bounds check triggers an out-of-bounds read that crashes the handling process, denying service. No user interaction is required. No public exploit code has been identified, and exploitation is rated non-automatable.

AnalysisAIv1 – Oct 05, 2026

Out-of-bounds read in Google Android's MMS PDU parsing code (PduParser.java) allows a remote attacker who can deliver a crafted or malformed Protocol Data Unit to the device to trigger a denial of service against the affected messaging/telephony component, with no user interaction required. Affected platforms are Android 14, 15, 16, 16-qpr2 and 17, per the EUVD version list and the wildcard CPE cpe:2.3:a:google:android:*; the vulnerability is rated CVSS 6.5 (MEDIUM), though independent review downgrades the availability impact to Low and confirms confidentiality and integrity are unaffected, with no code execution possible. No public exploit code has been identified and SSVC rates the issue as non-automatable with exploitation status 'none', so this is assessed as a moderate, low-priority denial-of-service hardening issue rather than an urgent threat.

RemediationAI

Patch status: patch available per vendor advisory - apply the Android Security Bulletin for October 2026 (2026-10-01 patch level or later), documented at https://source.android.com/docs/security/bulletin/2026/2026-10-01; the provided data does not include an individual commit hash or a component-specific patch level, so administrators should confirm the device reports the 2026-10-01 (or later) security patch level rather than assuming any single build is fixed. Because this is a local-platform fix distributed through OEM/carrier update channels, Android Enterprise administrators should prioritize this within normal monthly maintenance rather than as an emergency, given the assessed Low availability impact and no known exploitation. Compensating controls, if patching must be deferred: disable automatic MMS retrieval/auto-download in the default messaging app (trade-off: MMS messages are no longer previewed automatically, and the user must manually download them, shifting the decision to the user but also reducing the attack surface); where MMS is not business-critical, block MMS at the carrier/APN or MDM level or disable the messaging app entirely for managed profiles (trade-off: loss of picture/video messaging); and restrict routing of inbound MMS from untrusted senders via carrier controls where available (trade-off: potential loss of legitimate messages, and no protection against attacks delivered through other PDU-bearing interfaces). None of these workarounds fully substitute for the vendor patch, since any code path that still parses attacker-supplied PDUs remains reachable.

Technical ContextAI · show details

PduParser.java is part of Android's messaging stack, responsible for decoding binary Protocol Data Units (PDUs) used by SMS/MMS encapsulation (WSP/MMS-style length-prefixed structures). The flaw is classified CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and arises because one or more parsing routines in PduParser.java consume length or offset fields from the untrusted PDU without validating that the referenced data stays within the backing buffer, producing an out-of-bounds read. The practical consequence is a crash or mis-parse of the messaging component (availability loss only), not memory corruption leading to code execution, which is consistent with the C:N/I:N/A:H vector in the published CVSS and with our independent assessment narrowing availability impact to Low. Note a data conflict relevant to exploitation prerequisites: the published vector uses PR:L (privilege required), while the vendor description states no additional execution privileges are needed; our re-assessment uses PR:N/UI:N, but this privilege requirement remains unverified and should not be treated as settled. SSVC additionally rates the issue non-automatable, meaning mass opportunistic exploitation of the vulnerable code path is not expected.

Attack Technique

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
