hardware: Micro-architectural Load Port Data Sampling - Information Leak (MLPDS)

Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results ar...

QEMU: device_tree: heap buffer overflow while loading device tree blob

A heap buffer overflow issue was found in the loaddevicetree function of QEMU, which is invoked to load a device tree blob at boot time. It occurs due to device tree size manipulation before buffer allocation, which could overflow a signed int type. A user/process could use this flaw to potential...

JDK: Read beyond the end of bytecode array causing JVM crash

In Eclipse OpenJ9 prior to the 0.14.0 release, the Java bytecode verifier incorrectly allows a method to execute past the end of bytecode array causing crashes. Eclipse OpenJ9 v0.14.0 correctly detects this case and rejects the attempted class load...
