What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: i2c: mux: Fix channel node leak on adapter add failure i2c_mux_add_adapter() takes a reference to the Device Tree channel node before registering the new adapter. If adapter registration fails, the error path frees the private data without dropping that reference. Release the channel node before freeing the private data.

Source: EUVD (ENISA), in the words of the advisory.

Patchlage reports hits and suspected hits. About everything else this system says nothing — neither this page nor the situation report ever claims that an estate is safe.
