CVE-2018-5953

CVE-2018-5953 concerns the Linux kernel vulnerability where the function swiotlb_print_info (lib/swiotlb.c) in kernels up to 4.14.14 can leak sensitive address information via a software IO TLB printk in dmesg, exploitable by a local attacker. The connected Nessus entries for Unity Linux 20.x (ke...

CVE-2017-18202

The CVE-2017-18202 issue affects the Linux kernel prior to 4.14.4, where __oom_reap_task_mm in mm/oom_kill.c mishandles gather operations. This can enable a local attacker to cause a denial of service via a TLB entry leak or use-after-free, potentially with other unspecified impacts by triggering...

Information leak via side effects of speculative execution

ISSUE DESCRIPTION Processors give the illusion of a sequence of instructions executed one-by-one. However, in order to most efficiently use cpu resources, modern superscalar processors actually begin executing many instructions in parallel. In cases where instructions depend on the result of...

SUSE SLED12 / SLES12 Security Update : xen (SUSE-SU-2017:2864-1)

This update for xen fixes several issues: These security issues were fixed : - CVE-2017-5526: The ES1370 audio device emulation support was vulnerable to a memory leakage issue allowing a privileged user inside the guest to cause a DoS and/or potentially crash the Qemu process on the host...

Xen Hypervisor TLB Flush Request Handling Race Condition System Memory Access Guest-to-Host Privilege Escalation (XSA-241)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a race condition that is triggered when handling TLB flush requests. This allows an attacker on the guest to access all system memory, allowing them to cause a denial of service, disclose...
