CVE-2024-56782
Description
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.
