What is CVE-2026-22107?
A use-after-free vulnerability exists in the Android binder IPC driver (drivers/android/binder.c) in the transaction buffer release path. Improper reference counting during binder_thread cleanup leads to a dangling pointer to a freed binder_transaction object. An attacker with application-level code execution can exploit this via cross-cache memory reallocation techniques to reclaim the freed object with a controlled kernel structure, obtaining arbitrary kernel read/write primitives. Successful exploitation escalates privileges from application context to kernel, enabling SELinux bypass, credential structure modification, and full root access. The vulnerability affects GKI kernel versions 5.10, 5.15, and 6.1 used across Android 12 through 15. Google TAG identified this as Stage 2 of the Saito Tech (Candiru) commercial spyware exploit chain, chained after CVE-2026-22104 for privilege escalation.
The record classifies CVE-2026-22107 under weakness class CWE-416. Its CVSS v3 base vector states that the flaw requires local access to the host, needs low-privilege credentials, needs no user interaction, and has high impact on confidentiality, integrity. 5 affected-product entries are recorded, across 1 vendor, listed below.
