CVE-2022-49046

CVE-2022-49046 affects the Linux kernel i2c subsystem, specifically the dev: how the device name is set. The root cause is a missing check of the return value from dev_set_name(); if dev_set_name() fails, dev_name() may be null, leading to a potential null pointer dereference. The connected advis...
