CVE-2017-11472

High
Published: Translated: NVD NIST

Summary

The acpi_ns_terminate() function in the Linux kernel before version 4.12 does not flush the operand cache, leading to a kernel stack dump. This allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism.

Risk Assessment

The organization may be exposed to leakage of sensitive data from kernel memory, potentially leading to serious security breaches. The ability for attackers to bypass KASLR increases the risk of system exploitation.

Recommendation

It is recommended to update the Linux kernel to version 4.12 or later to mitigate this vulnerability. Additionally, monitoring and restricting access for local users can help minimize risk.

Original NVD description (English source)

The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel before 4.12 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.
