# libva: uncontrolled search path lets a local user escalate privilege

Link for people: https://infrastack.ai/live/CVE-2026-56438 (this .md is for agents)

libva, the Video Acceleration API library used on Linux for hardware video decoding, loads a library through an uncontrolled search path. A local user with an account can exploit this to escalate privileges, with a high-complexity attack that needs active user interaction.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Uncontrolled search path for the libva software for all versions within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires active user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
