  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/panthor: skip zero-sized firmware sections\n\npanthor_fw_load_section_entry() skips BO creation when the firmware section\nVA range is empty. If such a section is added to the firmware section list,\nsection-\u003emem is left as NULL.\n\nLater reload and unplug paths iterate over all firmware sections and\ndereference section-\u003emem, which can lead to a NULL pointer dereference.\n\nZero-sized firmware sections are valid, so accept them as no-op entries but\nskip adding them to the section list.",
