  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nsoc: microchip: mpfs: Fix memory leak in mpfs_sys_controller_probe()\nIn mpfs_sys_controller_probe(), if of_get_mtd_device_by_node() fails,\nthe function returns immediately without freeing the allocated memory\nfor sys_controller, leading to a memory leak.\nFix this by jumping to the out_free label to ensure the memory is\nproperly freed.\nAlso, consolidate the error handling for the mbox_request_channel()\nfailure case to use the same label.", "A flaw was found in the Linux kernel, specifically within the Microchip PolarFire SoC (System-on-Chip) system controller driver. When the `mpfs_sys_controller_probe()` function fails to initialize a device, it does not properly release allocated memory. This memory leak can accumulate over time, potentially leading to system instability or a denial of service (DoS) condition, where legitimate system operations are disrupted." ],
