CVE-2024-58011 Information

Description

In the Linux kernel the following vulnerability has been resolved:

platform/x86: int3472: Check for adev == NULL

Not all devices have an ACPI companion fwnode so adev might be NULL. This can e.g. (theoretically) happen when a user manually binds one of the int3472 drivers to another i2c/platform device through sysfs.

Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().
