Title
net: wwan: iosm: fix memory leak in ipc_pcie_read_bios_cfg
Summary
In the Linux kernel, the following vulnerability has been resolved: net: wwan: iosm: fix memory leak in ipc_pcie_read_bios_cfg ipc_pcie_read_bios_cfg() is using the acpi_evaluate_dsm() to obtain the wwan power state configuration from BIOS but is not freeing the acpi_object. The acpi_evaluate_dsm() returned acpi_object to be freed. Free the acpi_object after use.
