CVE-2018-18397

The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file if the user has read-only access to that file, and that file contains holes, related to...

CVE-2018-18397

The vulnerability CVE-2018-18397 affects the Linux kernel prior to 4.19.7, where the userfaultfd implementation mishandles access control for certain UFFDIO ioctls (fs/userfaultfd.c and mm/userfaultfd.c). A local attacker with read permissions on a tmpfs file containing holes could write data int...

Stack overflow

Local attackers can trigger a stack-based buffer overflow on vulnerable installations of Antiy-AVL ATool security management v1.0.0.22. 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...

CVE-2018-19085

RegFilter.sys in IOBit Malware Fighter 6.2 is susceptible to a stack-based buffer overflow when an attacker uses IOCTL 0x8006E048 with a size larger than 8 bytes. This can lead to denial of service or code execution with root privileges...

Cheetah Free WIFI 5.1 suffers from Denial of Service Vulnerability

Cheetah Free WiFi for PC is a free, minimalist wireless router. Cheetah Free WIFI 5.1 suffers from a denial of service vulnerability that originates from the driver liebaonat64.sys failing to perform strict checksums on incoming data during the processing of the ioctl code 0x830020E0 interface,...

Advantech WebAccess Client bwswfcfg Stack-based Buffer Overflow Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Advantech WebAccess Client. Authentication is not required to exploit this vulnerability. The specific flaw exists within bwswfcfg.exe, which is accessed through the 0x2711 IOCTL in the webvrpcs...

kernel: incorrect memory bounds check in drivers/cdrom/cdrom.c

A flaw was found in the Linux kernel, before 4.16.6 where the cdromioctlmediachanged function in drivers/cdrom/cdrom.c allows local attackers to use a incorrect bounds check in the CDROM driver CDROMMEDIACHANGED ioctl to read out kernel memory...

kernel: v4l2: disabled memory access protection mechanism allowing privilege escalation

A bug in the 32-bit compatibility layer of the ioctl handling code of the v4l2 video driver in the Linux kernel has been found. A memory protection mechanism ensuring that user-provided buffers always point to a userspace memory were disabled, allowing destination address to be in a kernel space...

DEBIAN-CVE-2018-18710

An issue was discovered in the Linux kernel through 4.19. An information leak in cdromioctlselectdisc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and...
