5th percentile - higher than 5% of all known CVEs

Summary

In the sec boot component, there is a possible escalation of privilege due to a heap buffer overflow. This could lead to local escalation of privilege if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is not required for exploitation.

Risk Assessment

An attacker with physical access could gain higher privileges, potentially bypassing boot security and gaining full device control.

Recommendation

Apply the appropriate patch (AUTO00845351 or ALPS11072643) depending on the chipset model.
