Linux kernel is vulnerable to denial of service(DoS) attacks. The xfs_dinode_verify
function in fs/xfs/libxfs/xfs_inode_buf.c
in the Linux kernel could cause a NULL pointer dereference in xfs_ilock_attr_map_shared
function. An attacker could exploit this by mounting a crafted xfs filesystem image to cause a kernel panic.
