DEBIAN-CVE-2018-20669
An issue where a provided address with accessok is not checked was discovered in i915gemexecbuffer2ioctl in drivers/gpu/drm/i915/i915gemexecbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a...
CVE-2018-20669: Improper Input Validation
An issue where a provided address with accessok is not checked was discovered in i915gemexecbuffer2ioctl in drivers/gpu/drm/i915/i915gemexecbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a...
CVE-2018-14745
CVE-2018-14745 affects the bcmdhd4358 Wi‑Fi driver in the Samsung Galaxy S6 (SM-G920F). The flaw is a buffer overflow in prot_get_ring_space caused by improper validation of the ring buffer read pointer, enabling an attacker who already has code execution on the Wi‑Fi chip to overwrite kernel mem...
CVE-2018-14745: Improper Restriction of Operations within the Bounds of a Memory Buffer
Buffer overflow in protgetringspace in the bcmdhd4358 Wi-Fi driver on the Samsung Galaxy S6 SM-G920F G920FXXU5EQH7 allows an attacker who has obtained code execution on the Wi-Fi chip to overwrite kernel memory due to improper validation of the ring buffer read pointer. The Samsung ID is...
Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2018-029)
According to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - An industry-wide issue was found in the way many modern microprocessor designs have implemented...
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...
Memory corruption
In Android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, there is a memory allocation without a length field validation in the mobicore driver which can result in an undersize buffer allocation. Ultimately this can result in a kernel memory...
CVE-2017-1000255
On Linux running on PowerPC hardware Power8 or later a user process can craft a signal frame and then do a sigreturn so that the kernel will take an exception interrupt, and use the r1 value from the signal frame as the kernel stack pointer. As part of the exception entry the content of the signa...

CVE-2017-8253
In all Qualcomm products with Android releases from CAF using the Linux kernel, kernel memory can potentially be overwritten if an invalid master is sent from userspace...
kernel: State machine confusion bug in vfio driver leading to memory corruption
A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution...
kernel: infiniband: Unprivileged process can overwrite kernel memory using rdma_ucm.ko
A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write as bi-directional ioctl replacement, which could lead to insufficient memory security checks when being invoked using the splice system call. A local unprivileged user on a system with either...
Linux kernel denial of service vulnerability (CNVD-2016-03199)
Linux kernel is an open source operating system. The Linux kernel 'fillv4l2buffer' function fails to properly validate the number of 'planes', allowing a local attacker to exploit this vulnerability to overwrite kernel memory and conduct denial of service attacks...

Null pointer dereference
The doexit function in kernel/exit.c in the Linux kernel before 2.6.36.2 does not properly handle a KERNELDS getfs value, which allows local users to bypass intended accessok restrictions, overwrite arbitrary kernel memory locations, and gain privileges by leveraging a 1 BUG, 2 NULL pointer...

CVE-2010-1446: Undefined Security Weakness
arch/powerpc/mm/fslbookemmu.c in KGDB in the Linux kernel 2.6.30 and other versions before 2.6.33, when running on PowerPC, does not properly perform a security check for access to a kernel page, which allows local users to overwrite arbitrary kernel memory, related to Fsl booke...
CVE-2009-1235: Undefined Security Weakness
XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving...
CVE-2009-1041: Improper Restriction of Operations within the Bounds of a Memory Buffer
The ktimer feature sys/kern/kerntime.c in FreeBSD 7.0, 7.1, and 7.2 allows local users to overwrite arbitrary kernel memory via an out-of-bounds timer value...
