ACPICA commit 8b14afac65d983610cc5387ede6d85ea5ee075be
The following ACPI table contains an invalid target node within the
Alias operator:
definition_block ("", "SSDT", 1, "Bug", "BugTable", 0x00001000)
{
Scope (_SB)
{
Device (DEV0)
{
Name (_ADR, 1)
Device (DEV1)
{
Alias (_ADR, _ADR)
}
}
}
}
If an ACPI table contains such an invalid target node in an Alias
operator, a segmentation fault will occur when the target node is
dereferenced within acpi_ex_create_alias. Add a check for such an invalid
target node in acpi_ex_create_alias and return AE_NULL_OBJECT as suggested
by @acpibob.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
