kernel: filesystem corruption due to an unchecked error condition during an xfs attribute change

In the Linux kernel before 4.17, a local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfsattrshortformaddname in fs/xfs/libxfs/xfsattr.c...

kernel: Invalid pointer dereference in xfs_ilock_attr_map_shared() when mounting crafted xfs image allowing denial of service

The xfsdinodeverify function in fs/xfs/libxfs/xfsinodebuf.c in the Linux kernel can cause a NULL pointer dereference in xfsilockattrmapshared 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 kerne...
