CVE-2026-81017

Description

A flaw was found in the Linux kernel's sensorhub component. A local attacker could provide a maliciously crafted sensor number in an EC FIFO event. This unchecked sensor number could lead to an out-of-bounds read and write in the batch_state array, potentially causing memory corruption or system instability.

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.
