CVE-2023-54190

In CVE-2023-54190, the Linux kernel fixes a refcount leak in leds-core: of_led_get() where class_find_device_by_of_node() previously took a reference via class_find_device() and relied on put_device() to drop it. The vulnerability pertains to the LED subsystem's reference counting and has been mi...

CVE-2022-50825

CVE-2022-50825 relates to a Linux kernel USB Type-C wusb3801 refcount leak in the wusb3801_probe path. The vulnerability arises from unbalanced of_node_get()/of_node_put() calls, described as a memory leak if wusb3801_hw_init() fails, where fwnode_handle_put() must be invoked to avoid the leak. C...
