Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.12.9 Linux kernel versions prior to 4.9

Description The issue is related to the acpi ns evaluate() function in the Linux kernel, which does not properly flush the operand cache. This can cause a kernel stack dump, allowing local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism.

Recommendations For Linux kernel versions prior to 4.12.9, update to version 4.12.9 or later to resolve the issue. For Linux kernel versions prior to 4.9, update to version 4.9 or later to strengthen the KASLR protection mechanism.
