CVE-2022-49855

CVE-2022-49855 affects the Linux kernel wwan driver (net: wwan: iosm). The root cause is that ipc_pcie_read_bios_cfg() uses acpi_evaluate_dsm() to obtain BIOS power-state config but fails to free the returned acpi_object, causing a memory leak. The issue has been resolved by freeing the acpi_obje...
