Description

The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image. The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel can cause a NULL pointer dereference in xfs_bmapi_write function. An attacker could trick a legitimate user or a privileged attacker could exploit this by mounting a crafted xfs filesystem image to cause a kernel panic and thus a denial of service.
