Accessories and Display Manager: Use of Hard-coded Cryptographic Key
CVE-2026-63423 is a high-severity use of hard-coded cryptographic key vulnerability in Accessories and Display Manager from Lenovo, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 1.0.9 as the first without the flaw, so updating Accessories and Display Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Accessories and Display Manager to 1.0.9 or a later version.
