CVE-2022-25368

CVE-2022-23960 describes Spectre-BHB: an attack on ARM Cortex and Neoverse CPUs that abuse the Branch History Buffer (BHB) to influence mispredicted branches, enabling a cache-related side-channel and potential information disclosure across security contexts. Affected: ARM Cortex and Neoverse pro...

CVE-2018-12130

A flaw was found in the implementation of the "fill buffer", a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer...

Traffic Analysis of Home Security Cameras

Interesting research on home security cameras with cloud storage. Basically, attackers can learn very basic information about what's going on in front of the camera, and infer when there is someone home. News article. Slashdot thread...
