Positive Technologies · (AI Summary)

**Name of the Vulnerable Software and Affected Versions:**

Linux kernel (affected versions not specified)

**Description:**

A flaw exists in the Linux kernel's crypto/caam module that can lead to a system crash during suspend operations on iMX8QM and iMX8ULP SoCs. This occurs because the CAAM on these systems is managed by another ARM core (SECO on iMX8QM and Secure Enclave on iMX8ULP) which reserves access to register page 0. The vulnerability is triggered when suspend operations attempt to access this reserved page. A new state variable, `no page0`, has been introduced to track whether page 0 is reserved, preventing access during suspend.

**Recommendations:**

At the moment, there is no information about a newer version that contains a fix for this vulnerability.
