Описание
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix uninitialized pointer free in add_inode_ref()
The add_inode_ref() function does not initialize the "name" struct when it is declared. If any of the following calls to "read_one_inode() returns NULL,
then "name.name" would be freed on "out" before being initialized.
out: ... kfree(name.name);
This issue was reported by Coverity with CID 1526744.
