MEDIUM 6.7EPSS 0.24%

Does this matter?

Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.

Description

Trusty contains a vulnerability in the HDCP service TA where bounds checking in command 9 is missing. Improper restriction of operations within the bounds of a memory buffer might lead to escalation of privileges, information disclosure, and denial of service.
