Description

In the Linux kernel, the following vulnerability has been resolved: power: supply: cpcap-battery: Fix missing nvmem_device_put() causing reference leak In cpcap_battery_detect_battery_type(), the reference to an nvmem device obtained via nvmem_device_find() is not released with nvmem_device_put() on the success or read-failure paths, causing a permanent reference leak. The driver’s retry logic on subsequent battery property reads can compound this leak, preventing the nvmem device from ever being freed. Found by code review.
