Alert meAnalysisAIv1 – Sep 15, 2026
An out-of-bounds write in the NXP NFC hardware abstraction layer (phNxpNciHal_ext_process_nfc_init_rsp in phNxpNciHal_ext.cc) lets a local attacker corrupt memory beyond the intended buffer while the HAL processes an NFC initialization response. Affected are Android devices that ship the NXP NFC HAL, which the Android CPE lists without a version bound; the flaw requires no user interaction and, per Google's bulletin wording, no additional execution privileges, so a typical app-level foothold is enough to attempt escalation. There is no CISA KEV listing and no public exploit code reported in the supplied intelligence, so exploitation is assessed as feasible but not yet observed.

Lifecycle Timeline
2DescriptionCVE.org
In phNxpNciHal_ext_process_nfc_init_rsp of phNxpNciHal_ext.cc, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Priority Score
Attack Technique
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
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.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
