An attacker who can execute code on the device can cause the function to grant higher privileges than intended without needing additional execution rights.

The EPSS score is reported as less than 1%, indicating a low probability of widespread exploitation at this time, and it is not included in CISA\u2019s KEV catalog. The attack requires local access; no network or elevated privileges are needed to trigger the bug.
