CVE-2024-56782

Estado: ModificadaMedia (5.5)—

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.
