In LimitRealloc of malloc_limit.cpp, there is a possible use after free due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in Android's memory allocator affects versions 14 through 17, enabling a low-privileged process to gain elevated system privileges without any user interaction. The root cause is a logic error in the LimitRealloc function within malloc_limit.cpp that produces a use-after-free condition, granting full confidentiality, integrity, and availability impact upon successful exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Initial local code execution at a low privilege level is required - for example, via a malicious installed application or local shell access on the Android device (consistent with CVSS PR:L and AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, score 7.8) accurately characterizes this as a local, low-complexity privilege escalation requiring only minimal prior access - consistent with the description's statement that no additional execution privileges are needed beyond initial local presence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the September 2026 Android Security Patch Level (2026-09-01) or later, which addresses this vulnerability as documented in Google's Android Security Bulletin at https://source.android.com/docs/security/bulletin/2026/2026-09-01. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Android devices running versions 14, 15, 16, or 17 across your organization and supported BYOD environments. …
