  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: cpcap-battery: Fix missing nvmem_device_put() causing reference leak\n\nIn cpcap_battery_detect_battery_type(), the reference to an nvmem\ndevice obtained via nvmem_device_find() is not released with\nnvmem_device_put() on the success or read-failure paths, causing a\npermanent reference leak. The driver\u2019s retry logic on subsequent\nbattery property reads can compound this leak, preventing the nvmem\ndevice from ever being freed.\n\nFound by code review.",
