AI-suggested
An official patch is available and should be applied promptly. After updating the Linux kernel to the fixed versions, a system reboot is required to activate the changes. No additional mitigation actions are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's hp-bioscfg driver allowed out-of-bounds array access during ACPI package parsing due to improper bounds checking. This flaw was fixed by correcting the bounds validation to include the additional offset used in array indexing. The issue affects multiple specific Linux kernel versions and has a CVSS score of 7.1, indicating a medium severity. The vulnerability could lead to denial of service and confidentiality loss but requires local privileges to exploit. A patch is available and should be applied, followed by a system reboot.
