Exploitation Probability (EPSS)

Low risk

0.23%

13th percentile - higher than 13% of all known CVEs

Summary

In the DA component, there is a possible out-of-bounds write due to a missing bounds check. This could lead to local denial of service 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 cause a system crash, potentially rendering the device unusable.

Recommendation

Apply the appropriate patch (ALPS10991588 or AUTO00851171) depending on the chipset model.
