CVE-2018-1108 – Linux RNG Flaws
https://notcve.org/view.php?id=CVE-2018-1108
kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated. Los controladores de kernel, en versiones anteriores a la 4.17-rc1, son vulnerables a una debilidad en la implementación del kernel de Linux de datos de semilla aleatorios. Los programas, en un estado de arranque temprano, podrían emplear los datos asignados a la semilla antes de que se haya generado lo suficiente. There are several issues in drivers/char/random.c, in particular related to the behavior of the /dev/urandom RNG during and shortly after boot. • http://www.securityfocus.com/bid/104055 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1108 https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://usn.ubuntu.com/3718-1 https://usn.ubuntu.com/3718-2 https://usn.ubuntu.com/3752-1 https://usn.ubuntu.com/3752-2 https://usn.ubuntu.com/3752-3 https://www.debian.org/security/2018/dsa-4188 • CWE-330: Use of Insufficiently Random Values •
CVE-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 •
CVE-2018-10323
https://notcve.org/view.php?id=CVE-2018-10323
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. La función xfs_bmap_extents_to_btree en fs/xfs/libxfs/xfs_bmap.c en el kernel de Linux, hasta la versión 4.16.3, permite que usuarios locales provoquen una denegación de servicio (desreferencia de puntero NULL en xfs_bmapi_write) mediante una imagen xfs manipulada. • http://www.securityfocus.com/bid/103959 https://bugzilla.kernel.org/show_bug.cgi?id=199423 https://usn.ubuntu.com/3752-1 https://usn.ubuntu.com/3752-2 https://usn.ubuntu.com/3752-3 https://usn.ubuntu.com/3754-1 https://usn.ubuntu.com/4486-1 https://www.debian.org/security/2018/dsa-4188 https://www.spinics.net/lists/linux-xfs/msg17254.html • CWE-476: NULL Pointer Dereference •
CVE-2018-10074

The hi3660_stub_clk_probe function in drivers/clk/hisilicon/clk-hi3660-stub.c in the Linux kernel before 4.16 allows local users to cause a denial of service (NULL pointer dereference) by triggering a failure of resource retrieval. La función hi3660_stub_clk_probe en drivers/clk/hisilicon/clk-hi3660-stub.c en el kernel de Linux, en versiones anteriores a la 4.16, permite que usuarios locales provoquen una denegación de servicio (desreferencia de puntero NULL) al desencadenar un error de recuperación de recursos. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9903e41ae1f5d50c93f268ca3304d4d7c64b9311 https://github.com/torvalds/linux/commit/9903e41ae1f5d50c93f268ca3304d4d7c64b9311 • CWE-476: NULL Pointer Dereference •
CVE-2018-10021
https://notcve.org/view.php?id=CVE-2018-10021
drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to cause a denial of service (ata qc leak) by triggering certain failure conditions. NOTE: a third party disputes the relevance of this report because the failure can only occur for physically proximate attackers who unplug SAS Host Bus Adapter cables ** EN DISPUTA ** drivers/scsi/libsas/sas_scsi_host.c en el kernel de Linux en versiones anteriores a la 4.16 permite que los usuarios locales provoquen una denegación de servicio (ata qc leak) al desencadenarse una serie de condiciones de fallo. NOTA: un tercero discute la relevancia de este informe debido a que el error solo puede ocurrir para atacantes físicamente cercanos que desconectan los cables SAS Host Bus Adapter. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=318aaf34f1179b39fa9c30fa0f3288b645beee39 https://bugzilla.suse.com/show_bug.cgi?id=1089281 https://github.com/torvalds/linux/commit/318aaf34f1179b39fa9c30fa0f3288b645beee39 https://lists.debian.org/debian-lts-announce/2018/07/msg00020.html https://usn.ubuntu.com/3678-1 https://usn.ubuntu.com/3678-2 https://usn.ubuntu.com/3678-3 https://usn.ubuntu.com/3678-4 https://usn.ubuntu.com/3696-1 https://usn.ubuntu •
