Android Kernel EUVD-2026-79161

Requires the attacker to already possess System execution privileges on the device and local access to reach the vulnerable addr_remap_address_map code path in remap.c; no user interaction is needed. Limiting factors are significant: the PR:H prerequisite means the attacker must already have compromised a highly privileged context, exploitation is local-only (no network vector), and the affected component is tied to Android/Pixel builds patched in the 2026-09-01 bulletin.

This is a genuine but bounded local privilege-escalation issue, not a top-tier emergency. The CVSS 3.1 vector (AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H, base 6.7) is internally consistent with the description: exploitation is strictly local, needs no user interaction, but requires the attacker to already hold System execution privileges (PR:H) - a very high bar that already implies substantial compromise. The reward for crossing that bar (a logic error in addr_remap_address_map allowing further privilege escalation) is therefore incremental, and the C:H/I:H/A:H impacts read as generous given the attacker is already running as System. Real-world exploitation signals are all cold: EPSS is 0.12% (2nd percentile), there is no CISA KEV listing, and no public POC was identified. No SSVC decision data was supplied. Net: real defect worth patching on the normal Android/Pixel monthly cadence, but the high privilege prerequisite plus negligible exploitation-probability signals place it well below internet-facing or unauthenticated flaws. No conflict between the CVSS vector and the description - both agree the vector is local and privilege-gated.

An attacker who has already achieved code execution in a System-privileged context on an Android/Pixel device invokes the flawed addr_remap_address_map path in remap.c and abuses the logic error to elevate beyond their current System boundary, all without any user interaction. No public exploit code was identified, so this remains a theoretical local-only chain rather than a demonstrated one.
