Android CVE-2025-48595: why the June 2026 patch date matters

CVE-2025-48595 has 2025 in its name, but the Android disclosure and repair discussed here arrived in June 2026. Google also reported indications of targeted exploitation. The identifier’s year is a poor shortcut for deciding whether a device has received the relevant fix.

What Google identifies

Google’s CVE description identifies integer overflows in multiple locations, possible code execution, and a local elevation-of-privilege impact without additional execution privileges or user interaction. The listed affected versions are Android 14, 15, 16 and 16-qpr2. The public description does not name the individual functions or disclose a complete causal sequence.

Google’s record for CVE-2025-48595

Android’s June bulletin reports indications of limited, targeted exploitation and gives June 5, 2026 or later as the patch level covering all of its issues. The bulletin also describes a critical remote Framework bug, CVE-2026-65018. That is a separate finding; its remote impact does not belong to CVE-2025-48595.

Android’s June 2026 security bulletin

CISA added this CVE to KEV on June 2, 2026, classifying it as an Android Framework integer overflow. That strengthens the reason to prioritize the update. It does not reveal the attacker’s initial access method.

When a bad number controls a memory operation

An integer overflow produces a value that no longer matches the intended arithmetic result. It becomes a security problem when later code trusts that value—for example, as a length, element count or storage capacity. Those quantities determine how much memory is reserved and accessed.

One documented weakness pattern is an integer overflow causing an undersized allocation, followed by an operation that exceeds the resulting buffer. MITRE catalogs that combination separately as CWE-680. This is an explanation of a possible relationship between arithmetic and memory corruption, not evidence that CVE-2025-48595 follows that exact pattern.

MITRE’s integer-overflow-to-buffer-overflow weakness chain

Track units as well as numbers. Element counts and byte counts are different, conversions can change what a validated length means, and a bound for one buffer may not protect a derived buffer. Individual checks can look reasonable while different layers still disagree about the same metadata.

Google says the overflows occur in multiple locations, but does not explain how those locations relate. There is no disclosed basis for choosing a specific parser, heap layout or attacker-controlled field as the cause. The public explanation can go as far as arithmetic safety and the reported privilege impact.

Local escalation does not identify the delivery route

Local elevation of privilege starts from a device-side context. The record does not tell us whether that context came from an app, website, physical interaction or another flaw. Each route would need its own evidence. No user interaction at this stage also does not establish a zero-click chain from beginning to end.

Android’s SELinux policy adds mandatory access controls to the traditional process-identity model. Even a process with substantial Unix privileges can still be restricted by its security domain. That is why an incident description should identify the authority actually obtained rather than reduce every outcome to “root.”

Android’s SELinux security model

For an incident assessment, identify the component that processed the input, the context executing the operation and the resources exposed afterward. The advisory leaves some of those questions open. Keep them open in the assessment rather than borrowing an explanation from a different Android exploit.

What belongs in the patch-verification record

Record the installed build after the update and required restart, not just the approval time in management software. If a device is unsupported, record the exposure and decide how to limit access to sensitive business resources while arranging replacement or another supported option.

Follow up on signs of targeting

An update repairs the covered software state. It does not revoke a copied session, identify accessed data or reconstruct earlier events. Where there is credible evidence of targeting, retain management and identity records and review affected accounts from a trusted device.

Engineers can use this case to review how size and capacity information passes between components. Operators have a different immediate task: verify that the actual device build contains the June 2026 correction.
