Side Channels Are Common

Really interesting research: "Lend Me Your Ear: Passive Remote Physical Side Channels on PCs." Abstract: We show that built-in sensors in commodity PCs, such as microphones, inadvertently capture electromagnetic side-channel leakage from ongoing computation. Moreover, this information is often...

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...
