CVE-2024-56782

In the Linux kernel, the following vulnerability has been resolved: ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration() acpi_dev_hid_match() does not check for adev == NULL, dereferencing it unconditional. Add a check for adev being NULL before calling acpi_dev_hid_match(). At the moment acpi_quirk_skip_serdev_enumeration() is never called with a controller_parent without an ACPI companion, but better safe than sorry.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ACPI: x86: Agregar comprobación de adev NULL a acpi_quirk_skip_serdev_enumeration() acpi_dev_hid_match() no comprueba si adev == NULL, lo desreferencia de forma incondicional. Agregue una comprobación para adev como NULL antes de llamar a acpi_dev_hid_match(). En este momento, acpi_quirk_skip_serdev_enumeration() nunca se llama con un controller_parent sin un compañero ACPI, pero más vale prevenir que curar.
