An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access. Un desbordamiento de enteros en la función qla2x00_sysfs_write_optrom_ctl en drivers/scsi/qla2xxx/qla_attr.c en el kernel de Linux hasta la versión 4.12.10 permite que los usuarios locales provoquen una denegación de servicio (corrupción de memoria y fallo de sistema) con acceso root. • http://www.securityfocus.com/bid/100571 https://bugzilla.kernel.org/show_bug.cgi?id=194061 https://lists.debian.org/debian-lts-announce/2017/12/msg00004.html https://patchwork.kernel.org/patch/9929625 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 • CWE-190: Integer Overflow or Wraparound •

The acpi_ps_complete_final_op() function in drivers/acpi/acpica/psobject.c in the Linux kernel through 4.12.9 does not flush the node and node_ext caches and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table. La función acpi_ps_complete_final_op() en drivers/acpi/acpica/psobject.c en el kernel Linux en su versión 4.12.9 no vacía las cachés node y node_ext y provoca un volcado de pila de kernel, lo que permite que usuarios locales obtengan información sensible de la memoria del kernel y omitan el mecanismo de protección KASLR (en la versión 4.9 del kernel) mediante una tabla ACPI manipulada. • http://www.securityfocus.com/bid/100500 https://github.com/acpica/acpica/pull/278/commits/4a0243ecb4c94e2d73510d096c5ea4d0711fc6c0 https://patchwork.kernel.org/patch/9806085 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVSS: 7.6EPSS: 0%CPEs: 13EXPL: 1CVE-2017-10661 – Linux kernel < 4.10.15 - Race Condition Privilege Escalation
https://notcve.org/view.php?id=CVE-2017-10661
Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing. Una condición de carrera en fs/timerfd.c en el kernel Linux en versiones anteriores a la 4.10.15 permite que usuarios locales obtengan privilegios o provoquen una denegación de servicio (corrupción de lista o use-after-free) mediante operaciones simultáneas de descriptor de archivo que aprovechan la cola inadecuada might_cancel. A race condition was found in the Linux kernel before version 4.11-rc1 in 'fs/timerfd.c' file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper 'might_cancel' queuing. An unprivileged local user could use this flaw to cause a denial of service of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • https://www.exploit-db.com/exploits/43345 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1e38da300e1e395a15048b0af1e5305bd91402f6 http://www.debian.org/security/2017/dsa-3981 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.10.15 http://www.securityfocus.com/bid/100215 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://access.redhat.com/errata/RHSA-2019:4057 https://access.redhat.com/e • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
