CVE-2025-48595
CVE-2025-48595 is a security flaw in Android Framework, Google’s operating system for phones and tablets. Attackers can run their own code on Android Framework. The US Cybersecurity and Infrastructure Security Agency (CISA) added it to its catalog of flaws known to be used in attacks on 2 Jun 2026.[1]
Android Framework is in things households have, such as phones, computers, browsers and everyday apps, so the fix matters at home as much as at work. Android has published a fix or advice.
Description
CISA calls it an integer overflow in Android Framework. In its words: “Android Framework contains an integer overflow vulnerability that allows for code execution that could allow for local privilege escalation.”[1]
The CVE record adds: “In multiple locations, there is a possible way to achieve code execution due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.”[2]
The underlying weakness is integer overflow (CWE-190), in MITRE’s list of common software weaknesses.
It scores 8.4 out of 10 on the Common Vulnerability Scoring System, which rates it high, scored by the organisation that published the CVE using CVSS 3.1.[2]
Affected versions
NVD’s record doesn’t list version ranges for it; Android’s advisory has them[3]. CISA names the product as Android Framework.
Every device with Android Framework needs the update.
Exploitation
CISA added it to its catalog of known exploited vulnerabilities on 2 Jun 2026, within a day of it being made public. CISA lists a flaw only when it has reliable evidence of it being exploited, and gave US federal agencies until 5 Jun 2026 to fix it.[1]
FIRST’s Exploit Prediction Scoring System, which estimates how likely a flaw is to be used in attacks in the next 30 days from what it sees across the internet, puts it at 2%. That’s in the top 20% of the flaws it scores.[4]
CISA assesses it as not automatable: each attack takes some work.
CISA doesn’t say who was attacked, or how.
Fix
Android has published a fix or advice.[3] CISA’s required action: “Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.”[1]
- Update Android Framework now.On Android: Settings, then System or Software update. Phones only get these fixes while their maker still supports them. Then turn on automatic updates, so the next fix arrives on its own.
- If there’s no update, stop using it.CISA’s advice when a flaw being used in attacks has no fix is to stop using the product until it does.
