AI description
CVE-2023-48010 affects STMicroelectronics SPC58 PowerPC microcontrollers. The vulnerability stems from a missing protection mechanism for an alternate hardware interface. Specifically, code running as Supervisor on the SPC58 PowerPC microcontrollers can disable the System Memory Protection Unit. This allows the code to gain unrestricted read/write access to protected assets.
