Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: fix uninitialized pointer free in add_inode_ref()<br /> <br /> The add_inode_ref() function does not initialize the "name" struct when<br /> it is declared. If any of the following calls to "read_one_inode()<br /> returns NULL,<br /> <br /> dir = read_one_inode(root, parent_objectid);<br /> if (!dir) {<br /> ret = -ENOENT;<br /> goto out;<br /> }<br /> <br /> inode = read_one_inode(root, inode_objectid);<br /> if (!inode) {<br /> ret = -EIO;<br /> goto out;<br /> }<br /> <br /> then "name.name" would be freed on "out" before being initialized.<br /> <br /> out:<br /> ...<br /> kfree(name.name);<br /> <br /> This issue was reported by Coverity with CID 1526744.
