A patch is available and should be applied to affected Linux kernel versions as per the Ubuntu security advisory USN-8876-1. Users should update their linux-hwe-edge kernel to a fixed version to remediate this vulnerability. No additional mitigations are specified by the vendor.
Description
A vulnerability in the Linux kernel's mtd: rawnand subsystem was fixed by correcting a condition in the 'nand_select_target()' function to ensure the 'cs' value is within the valid range. This flaw could allow a local attacker to cause significant impact including full confidentiality, integrity, and availability compromise. Multiple specific Linux kernel versions are affected. A patch is available to address this issue.
