Updated kernel packages fix security vulnerabilities

This kernel update is based on the upstream 4.14.89 and fixes at least the following security issues: Cross-hyperthread Spectre v2 mitigation is now provided by the Single Thread Indirect Branch Predictors STIBP support. Note that STIBP also requires the functionality be supported by the Intel...

kernel: vhost: Information disclosure in vhost/vhost.c:vhost_new_msg()

The Linux kernel does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhostnewmsg function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file...

Linux kernel information disclosure vulnerability (CNVD-2018-18597)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. An information disclosure vulnerability exists in the 'cdromioctldrivestatus' function in the drivers/cdrom/cdrom.c file in versions of the Linux kernel prior to 4.18....

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...

Design/Logic Flaw

The timercreate syscall implementation in kernel/time/posix-timers.c in the Linux kernel before 4.14.8 doesn't properly validate the sigevent-sigevnotify field, which leads to out-of-bounds access in the showtimer function called when /proc/$PID/timers is read. This allows userspace applications ...

UBUNTU-CVE-2018-1118

Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhostnewmsg function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-ne...

CVE-2018-4090

An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. macOS before 10.13.3 is affected. tvOS before 11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the "Kernel" component. It allows attackers to bypass intended memory-read restrictions via a...

PT-2018-6841 · Linux +5 · Linux Kernel +5

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.14.8 Description: The issue arises from improper validation of the sigevent-sigev notify field in the timer create syscall implementation. This leads to out-of-bounds access when the show timer function is...

Kernel: kvm: use after free in complete_emulated_mmio

arch/x86/kvm/emulate.c in the Linux kernel through 4.9.3 allows local users to obtain sensitive information from kernel memory or cause a denial of service use-after-free via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt...

CVE-2016-4628

IOAcceleratorFamily in Apple iOS before 9.3.3 and watchOS before 2.2.2 allows local users to obtain sensitive information from kernel memory or cause a denial of service out-of-bounds read via unspecified vectors...

The vulnerability of the Linux operating system’s kernel, which allows a hacker to gain access to confidential information

The vulnerability of the skrunfilter function net/core/filter.c in the Linux operating system is related to the lack of checks for the correctness of memory initialization before executing BPFSLDMEM and BPFSLDXMEM instructions. Exploiting this vulnerability can allow a local attacker to access...

DEBIAN-CVE-2016-5244

The rdsincinfocopy function in net/rds/recv.c in the Linux kernel through 4.6.3 does not initialize a certain structure member, which allows remote attackers to obtain sensitive information from kernel stack memory by reading an RDS message...

DEBIAN-CVE-2016-2117

The atl2probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data...
