Debian: CVE-2024-50088: linux, linux-6.1 -- security update

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);
