An out-of-bounds array access vulnerability in the Linux kernel ti-ads1298 driver allows local authenticated attackers to achieve high impact across confidentiality, integrity, and availability.

This is an out-of-bounds array access vulnerability involving the ti-ads1298 analog-to-digital converter driver, where an improperly validated index can be triggered by a local attacker with low privileges.

Successful exploitation of this kernel vulnerability can lead to total system compromise, including privilege escalation, arbitrary code execution, and kernel panics resulting in denial of service. The CVSS score of 7.8 reflects the high severity of the threat, though it requires local access and low privileges to execute. Left unpatched, this flaw exposes critical infrastructure and sensitive data stored on host systems to malicious actors.

Immediate Action: Update the Linux kernel to version 6.12.95, 6.18.37, 7.0.14, 7.1.2, or later where the bounds check validation fix is integrated.

Proactive Monitoring: Monitor system logs for unexpected kernel panics, segmentation faults, or unauthorized execution attempts originating from local user accounts.

Compensating Controls: Restrict local shell access and implement strict principle-of-least-privilege policies to minimize the pool of users who can interact with the affected hardware subsystem.

Public Exploit Available: No (there is no confirmed public exploit in the available data)

Administrators managing systems utilizing the ti-ads1298 hardware driver must prioritize applying the latest upstream kernel patches immediately. Securing local environments against unauthorized access remains critical to neutralizing the attack vector required for this vulnerability.
