Kernel: hw: cpu: L1 terminal fault (L1TF)

Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of...

Google Android has an unspecified vulnerability (CNVD-2019-44517)

Android is a Linux-based open source operating system jointly developed by Google and the Open Handheld Alliance OHA. A security vulnerability exists in Android that stems from the program not properly validating pointers in the ADSPRPC command. An attacker can exploit the vulnerability to access...

CVE-2018-5886

CVE-2018-5886 describes a vulnerability where a pointer in an ADSPRPC command is not properly validated in CAF Android builds using the Linux kernel (Android for MSM, Firefox OS for MSM, QRD Android). The root cause is improper validation of a pointer in the ADSPRPC path, which can allow access t...

kernel: mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism

The mm subsystem in the Linux kernel through 4.10.10 does not properly enforce the CONFIGSTRICTDEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte and bypass slab-allocation access restrictions via an application that opens the...

Linux kernel 'udl_fb_mmap' function integer overflow vulnerability

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An integer overflow vulnerability exists in the 'udlfbmmap' function in the drivers/gpu/drm/udl/udlfb.c file in Linux kernel versions 3.4 through 4.15. A local attacke...

CVE-2018-8781

The udlfbmmap function in drivers/gpu/drm/udl/udlfb.c at the Linux kernel version 3.4 and up to and including 4.15 has an integer-overflow vulnerability allowing local users with access to the udldrmfb driver to obtain full read and write permissions on kernel physical pages, resulting in a code...

CVE-2018-6917

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, insufficient validation of user-provided font parameters can result in an integer overflow, leading to the use of arbitrary kernel memory as glyph data. Unprivileged users may be able to access...

Safari Webkit Proxy Object Type Confusion

This module exploits a type confusion bug in the Javascript Proxy object in WebKit. The DFG JIT does not take into account that, through the use of a Proxy, it is possible to run arbitrary JS code during the execution of a CreateThis operation. This makes it possible to change the structure of e....

USN-3522-4 linux-lts-xenial regression

USN-3522-2 fixed a vulnerability in the Linux Hardware Enablement kernel for Ubuntu 14.04 LTS to address Meltdown CVE-2017-5754. Unfortunately, that update introduced a regression where a few systems failed to boot successfully. This update fixes the problem. We apologize for the inconvenience...

CVE-2017-9724

In all Qualcomm products with Android releases from CAF using the Linux kernel, user-level permissions can be used to gain access to kernel memory, specifically the ION cache maintenance code is writing to a user supplied address...

CVE-2017-13695

The acpinsevaluate function in drivers/acpi/acpica/nseval.c in the Linux kernel through 4.12.9 does not flush the operand cache 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 throu...

kernel: Use after free in SCSI generic device interface

It was found that the blkrqmapuseriov function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service use-after-free by leveraging write...

kernel: Use after free in SCSI generic device interface (CVE-2016-9576 regression)

It was found that the fix for CVE-2016-9576 was incomplete: the Linux kernel's sg implementation did not properly restrict write operations in situations where the KERNELDS option is set. A local attacker to read or write to arbitrary kernel memory locations or cause a denial of service...

Linux Kernel 'saa7164-bus.c' Local Elevation of Privilege Vulnerability

Linux is a free-to-use and freely distributed Unix-like operating system, a multi-user, multi-tasking, multi-threaded and multi-CPU supported operating system based on POSIX and UNIX. A local elevation of privilege vulnerability exists in Linux Kernel 'saa7164-bus.c'. A local attacker can exploit...

DEBIAN-CVE-2017-7889

The mm subsystem in the Linux kernel through 3.2 does not properly enforce the CONFIGSTRICTDEVMEM protection mechanism, which allows local users to read or write to kernel memory locations in the first megabyte and bypass slab-allocation access restrictions via an application that opens the...

MGASA-2017-0064 Updated kernel-tmb packages fixes security vulnerabilities

This kernel-tmb update is based on upstream 4.4.50 and fixes at least the following security issues: The cgroup offline implementation in the Linux kernel through 4.8.11 mishandles certain drain operations, which allows local users to cause a denial of service system hang by leveraging access to ...

SUSE-SU-2017:0245-1 Security update for Linux Kernel Live Patch 16 for SLE 12

This update for the Linux Kernel 3.12.60-5257 fixes several issues. The following security bugs were fixed: - CVE-2016-9806: Race condition in the netlinkdump function in net/netlink/afnetlink.c in the Linux kernel allowed local users to cause a denial of service double free or possibly have...
