CVSS: 7.8EPSS: 0%CPEs: 29EXPL: 0CVE-2018-10675 – kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact
https://notcve.org/view.php?id=CVE-2018-10675
The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls. La función do_get_mempolicy en mm/mempolicy.c en el kernel de Linux, en versiones anteriores a la 4.12.9, permite que los usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada) o, posiblemente, causen otros impactos no especificados mediante llamadas del sistema manipuladas. The do_get_mempolicy() function in mm/mempolicy.c in the Linux kernel allows local users to hit a use-after-free bug via crafted system calls and thus cause a denial of service (DoS) or possibly have unspecified other impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=73223e4e2e3867ebf033a5a8eb2e5df0158ccc99 http://www.securityfocus.com/bid/104093 https://access.redhat.com/errata/RHSA-2018:2164 https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2018:2785 https://access.redhat.com/errata/RHSA-2018:2791 https://access.redhat.com/errata/RHSA-2018:2924 https://access.redhat.com/errata/RHSA-2018& • CWE-416: Use After Free •

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 •
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 •

The arch_timer_reg_read_stable macro in arch/arm64/include/asm/arch_timer.h in the Linux kernel before 4.13 allows local users to cause a denial of service (infinite recursion) by writing to a file under /sys/kernel/debug in certain circumstances, as demonstrated by a scenario involving debugfs, ftrace, PREEMPT_TRACER, and FUNCTION_GRAPH_TRACER. La macro arch_timer_reg_read_stable en arch/arm64/include/asm/arch_timer.h en el kernel de Linux, en versiones anteriores a la 4.13, permite que usuarios locales provoquen una denegación de servicio (recursión infinita) escribiendo en un archivo en /sys/kernel/debug en ciertas circunstancias, tal y como se demuestra por un escenario que implica debugfs, ftrace, PREEMPT_TRACER y FUNCTION_GRAPH_TRACER. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=adb4f11e0a8f4e29900adb2b7af28b6bbd5c1fa4 https://github.com/torvalds/linux/commit/adb4f11e0a8f4e29900adb2b7af28b6bbd5c1fa4 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
