Linux kernel security vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel, which stems from the fact that maximum page sharing in Kernel Samepage Merging KSM can create side channels that may lead t...

SUSE CVE-2024-0564

A flaw was found in the Linux kernel's memory deduplication mechanism. The max page sharing of Kernel Samepage Merging KSM, added in Linux kernel version 4.4.0-96.119, can create a side channel. When the attacker and the victim share the same host and the default setting of KSM is "max page...

SUSE CVE-2015-2877

Kernel Samepage Merging KSM in the Linux kernel 2.6.32 through 4.x does not prevent use of a write-timing side channel, which allows guest OS users to defeat the ASLR protection mechanism on other guest OS instances via a Cross-VM ASL INtrospection CAIN attack. NOTE: the vendor states "Basically ...

SUSE CVE-2021-3714

A flaw was found in the Linux kernels memory deduplication mechanism. Previous work has shown that memory deduplication can be attacked via a local exploitation mechanism. The same technique can be used if an attacker can upload page sized files and detect the change in access time from a network...

CVE-2021-3714

CVE-2021-3714 (Linux kernel) affects the kernel’s memory deduplication mechanism. The connected sources describe a local-exploitation style attack where an adversary can upload page-sized files and observe access-time changes from a networked service to infer whether pages have been merged. This ...
