AI-suggested

A patch is available and should be applied to affected Linux kernel versions. Users should update their systems to the fixed kernel releases as provided by their distribution vendors, such as the Ubuntu security notice USN-7769-1. No additional mitigation steps are indicated beyond applying the official fix.

Description

A vulnerability in the Linux kernel's spi-rockchip driver allowed out-of-bounds register access due to improper handling of GPIO chip selects. This flaw was addressed by preventing writes to native chip select registers for GPIO chip selects, which can have higher numbering. The issue affects multiple specific Linux kernel versions and has been fixed in updated releases. The vulnerability has a CVSS score of 7.1, indicating a medium severity level, with high impact on confidentiality and availability but no known exploits in the wild. The vendor has released patches to remediate this issue.
