This vulnerability allows local attackers to escalate privileges on vulnerable installations of Kingsoft Internet Security. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaws exists within the processing of IOCTL 0x80030004 or 0x80030008 by the KWatch3.sys (internet security) kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in a kernel stack buffer overflow. An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel.
This module exploits a race condition vulnerability in the Linux Kernel via MAP_PRIVATE COW.



The bug relies in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.



This update improves the post-escalation execution.
The waitid implementation in upstream kernels did not restrict the target destination to copy information results. This can allow local users to write to otherwise protected kernel memory, which can lead to privilege escalation.

This update fixes the way non-vulnerable targets are handled

This vulnerability allows local attackers to escalate privileges on vulnerable installations of IKARUS anti.virus. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of crafted IOCTL 0x8300000c by the ntguard_x64.sys kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in an out-of-bounds write condition. An attacker can leverage this vulnerability to elevate privileges in context of kernel.
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Jungo WinDriver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.



The specific flaw exists within the processing of IOCTL 0x953824a7 by the windrvr12xx kernel driver. The issue lies in the failure to properly validate user-supplied data which can result in an out-of-bounds write condition. An attacker can leverage this vulnerability to execute arbitrary code under the context of kernel.
NVIDIA Windows GPU Display Driver R340 before 342.00 and R375 before 375.63 contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x600000D where a value passed from a user to the driver is used without validation leading to escalation of privileges. This update add reliability and speed to the attack.
