CVE-2022-50522: Linux kernel vulnerability

Linux · Linux Kernel

In the Linux kernel, the following vulnerability has been resolved: mcb: mcb-parse: fix error handing in chameleon_parse_gdd() If mcb_device_register() returns error in chameleon_parse_gdd(), the refcount of bus and device name are leaked. Fix this by calling put_device() to give up the reference, so they can be released in mcb_release_dev() and kobject_cleanup().
