There is no fixed version for RHEL:6 kernel-headers.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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,

dir = read_one_inode(root, parent_objectid);
if (!dir) {
    ret = -ENOENT;
    goto out;
}

inode = read_one_inode(root, inode_objectid); if (!inode) { ret = -EIO; goto out; }

then "name.name" would be freed on "out" before being initialized.

out: ... kfree(name.name);

This issue was reported by Coverity with CID 1526744.
