CVE-2022-50421

The CVE-2022-50421 entry concerns the Linux kernel rpmsg subsystem. The root cause is a double-destroy path for the default rpmsg endpoint: rpmsg_chrdev_eptdev_destroy() may destroy the default endpoint again after rpmsg_dev_remove() releases it, causing refcount underflow and use-after-free. Rep...
