CVE-2025-1865 (GCVE-0-2025-1865)

Vulnerability from cvelistv5 – Published: 2025-04-04 09:52 – Updated: 2025-07-07 20:49
VLAI?
Summary
The kernel driver, accessible to low-privileged users, exposes a function that fails to properly validate the privileges of the calling process. This allows creating files at arbitrary locations with full user control, ultimately allowing for privilege escalation to SYSTEM.
