A missing asynchronous flag in the Linux kernel Tegra crypto driver can lead to system crashes and potential high impact security risks when exploited by authenticated users.

This is an implementation flaw in the Tegra crypto driver where the CRYPTO_ALG_ASYNC flag is omitted, allowing low privileged authenticated users to cause crashes by forcing the crypto API to incorrectly select asynchronous algorithms for synchronous requests.

Successful exploitation of this vulnerability can result in kernel panics and denial of service conditions, causing unexpected system downtime and service disruption. With a CVSS score of 8.8, this flaw represents a severe risk to system stability and operational continuity, requiring prompt remediation.

Immediate Action: Update the Linux kernel to fixed versions including 6.12.81, 6.18.22, 6.19.12, or apply the corresponding vendor patches.

Proactive Monitoring: Monitor system logs for kernel panics, unexpected reboots, and related crypto driver error messages.

Compensating Controls: Restrict low privileged user access to the affected system environment and ensure strict least privilege principles are enforced.

Public Exploit Available: false

Given the high severity CVSS score and the risk of system instability, administrators should prioritize updating the Linux kernel to the latest fixed releases. Applying these vendor patches immediately will ensure system resilience and prevent potential crashes caused by improper cryptographic algorithm handling.
