UBUNTU-CVE-2019-17075

An issue was discovered in writetptentry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dmamapsingle a DMA function from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used ...

EulerOS Virtualization 3.0.1.0 : kernel (EulerOS-SA-2019-1475)

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - The skbflowdissect function in net/core/flowdissector.c in the Linux kernel through 3.12 allows remote attackers to cause a denia...

kernel: lack of check for mmap minimum address in expand_downwards in mm/mmap.c leads to NULL pointer dereferences exploit on non-SMAP platforms

A flaw was found in mmap in the Linux kernel allowing the process to map a null page. This allows attackers to abuse this mechanism to turn null pointer dereferences into workable exploits...

[SECURITY] Fedora 29 Update: libxmlb-0.1.8-2.fc29

XML is slow to parse and strings inside the document cannot be memory mappe d as they do not have a trailing NUL char. The libxmlb library takes XML source, and converts it to a structured binary representation with a deduplicated string table -- where the strings have the NULs included. This...

Summary: A potential security vulnerability in some microprocessors may allow information disclosure. Vulnerability Details: CVEID: CVE-2019-0162 Description: Memory access in virtual memory mapping for some microprocessors may allow an authenticated user to potentially enable information...

MGASA-2019-0120 Updated kernel packages fix security vulnerability

This kernel update is based on the upstream 4.14.106 and fixes at least the following security issue: In the Linux kernel before 4.20.14, expanddownwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on...

Linux < 4.20.14 - Virtual Address 0 is Mappable via Privileged write() to /proc/*/mem

By following the codepath that Andrea Arcangeli pointed out in his mails regarding the last bug I reported, I noticed that it is possible for userspace on a normal distro to map virtual address 0, which on an X86 system without SMAP enables the exploitation of kernel NULL pointer dereferences. Th...

Information Disclosure

kernel is vulnerable to information disclosure attacks. The vulnerability exists through an integer overflow in the fbmmap function in drivers/video/fbmem.c in the Linux kernel before 3.8.9, as used in a certain Motorola build of Android 4.1.2 and other products, allows local users to create a...

Xen elevation of privilege vulnerability (CNVD-2019-07941)

Xen is an open source virtual machine monitor developed by the Xen Project. An elevation of privilege vulnerability exists in 4.11.x and earlier versions of Xen on AMD x86 platforms, which stems from the failure of small IOMMU mappings to be securely combined into larger IOMMU mappings, which can...

Xen elevation of privilege vulnerability (CNVD-2019-07942)

Xen is an open source virtual machine monitor developed by the Xen Project. An elevation of privilege vulnerability exists in 4.11.x and earlier versions of Xen on AMD x86 platforms, which stems from the fact that a TLB refresh is sometimes not performed after an IOMMU mapping change, and can be...

An issue was discovered in Xen 4.11.x allowing x86 guest OS users to cause a denial of service host OS hang because the p2m lock remains unavailable indefinitely in certain error conditions...

kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service

By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the /proc//cmdline or /proc//environ files to block indefinitely...

UBUNTU-CVE-2018-17182

An issue was discovered in the Linux kernel through 4.18.8. The vmacacheflushall function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free and possibly gain privileges via certain thread creation, map, unmap, invalidation, and dereference operations...
