# Secure vector predicate and fault registers leak to non-secure callers

Link for people: https://infrastack.ai/live/CVE-2026-58810 (this .md is for agents)

Several functions in simd_ctx.c use uninitialized data, so secure vector predicate and fault register values can be read by non-secure callers. An attacker with local code running at System privilege could learn that register state.

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

## From the sources

In multiple functions of simd_ctx.c, there is a possible way to disclose secure vector predicate and fault registers to non-secure callers due to uninitialized data. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.
