Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.12.10 Linux kernel versions prior to 4.9 (for KASLR protection mechanism bypass)

Description The issue allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted ACPI table. This is caused by the acpi ds create operands() function in drivers/acpi/acpica/dsutils.c not flushing the operand cache, leading to a kernel stack dump.

Recommendations For Linux kernel versions prior to 4.12.10, update to version 4.12.10 or later to resolve the issue. For Linux kernel versions prior to 4.9, update to version 4.9 or later to prevent KASLR protection mechanism bypass. As a temporary workaround, consider restricting access to crafted ACPI tables until a patch is available.
