CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 1CVE-2018-10322 – kernel: Invalid pointer dereference in xfs_ilock_attr_map_shared() when mounting crafted xfs image allowing denial of service
https://notcve.org/view.php?id=CVE-2018-10322
The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_ilock_attr_map_shared invalid pointer dereference) via a crafted xfs image. La función xfs_dinode_verify en fs/xfs/libxfs/xfs_inode_buf.c en el kernel de Linux, hasta la versión 4.16.3, permite que usuarios locales provoquen una denegación de servicio (desreferencia de puntero inválido en xfs_ilock_attr_map_shared) mediante una imagen xfs manipulada. The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel can cause a NULL pointer dereference in xfs_ilock_attr_map_shared 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. • http://www.securityfocus.com/bid/103960 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://bugzilla.kernel.org/show_bug.cgi?id=199377 https://usn.ubuntu.com/4578-1 https://usn.ubuntu.com/4579-1 https://www.spinics.net/lists/linux-xfs/msg17215.html https://access.redhat.com/security/cve/CVE-2018-10322 https://bugzilla.redhat.com/show_bug.cgi?id=1571623 • CWE-476: NULL Pointer Dereference •
