In the Linux kernel, the following vulnerability has been resolved:

ext4: fix missing brelse() in ext4_xattr_inode_dec_ref_all()

The commit c8e008b60492 ('ext4: ignore xattrs past end')
introduced a refcount leak in when block_csum is false.

ext4_xattr_inode_dec_ref_all() calls ext4_get_inode_loc() to
get iloc.bh, but never releases it with brelse().
