Alert meAnalysisAIv1 – Mar 12, 2026
Local privilege escalation in Android's Media Framework Codec (MFC) decoder results from an out-of-bounds write vulnerability in the mfc_dec_dqbuf function due to inadequate bounds validation. An attacker with local access can exploit this defect without special privileges or user interaction to gain elevated system permissions. No patch is currently available for this vulnerability.
Earlier versions of this analysis (1)
In mfc_dec_dqbuf of mfc_dec_v4l2.c, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. [CVSS 8.4 HIGH]

Executive ViewAI
CVE-2026-0117 is a local privilege escalation vulnerability in media codec processing that allows authenticated local users to gain elevated system privileges. This poses a significant risk to organizations where untrusted users have local system access, potentially compromising sensitive data and system integrity.
Restrict local system access through privilege management and account controls; disable or restrict media decoding features in production environments where feasible; implement kernel hardening measures (SELinux/AppArmor) to limit privilege escalation impact; monitor process execution and system privilege changes for anomalous activity; segment systems processing untrusted media content from critical infrastructure.
