Sources and claim methodology

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: mtd: virt-concat: free duplicate generated name Every MTD registration runs mtd_virt_concat_create_join(). Once a virtual concat has already been registered, the function builds the same name again and takes the equal-name branch. That branch skips to the next item without freeing the newly allocated string. Free the temporary name before continuing.
