In the Linux kernel, the following vulnerability has been resolved:
ACPI: video: check for error while searching for backlight device parent
If acpigetparent() called in acpivideodevregisterbacklight() fails, for example, because acpiutacquiremutex() fails inside acpigetparent), this can lead to incorrect (uninitialized) acpiparent handle being passed to acpigetpci_dev() for detecting the parent pci device.
Check acpigetparent() result and set parent device only in case of success.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
