CVE-2024-35785
Description
A flaw was found in the Linux kernel's Trusted Execution Environment (TEE) subsystem, specifically within the Open Portable Trusted Execution Environment (OP-TEE) component. Incorrect error handling in this component can lead to a kernel panic, resulting in a denial of service. A local attacker could potentially exploit this vulnerability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
