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.
