CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2018-13093 – kernel: NULL pointer dereference in lookup_slow function
https://notcve.org/view.php?id=CVE-2018-13093
An issue was discovered in fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3. There is a NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that cached inodes are free during allocation. Se ha descubierto un problema en fs/xfs/xfs_icache.c en el kernel de Linux hasta la versión 4.17.3. Existe una desreferencia de puntero NULL y pánico en lookup_slow() en un puntero NULL inode->i_ops cuando se navega por rutas en una imagen xfs corrupta. • https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://bugzilla.kernel.org/show_bug.cgi?id=199367 https://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git/commit/?h=for-next&id=afca6c5b2595fc44383919fba740c194b0b76aff https://github.com/torvalds/linux/commit/afca6c5b2595fc44383919fba740c194b0b76aff https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://usn.ubuntu.com/4094-1 https://usn.ubuntu.com/4118-1 https://access.re • CWE-476: NULL Pointer Dereference •
