Spectre, Google, and the Universal Read Gadget

Spectre, a seemingly never ending menace to processors, is back in the limelight once again thanks to the Universal Read Gadget. First seen at the start of 2018, Spectre emerged alongside Meltdown as a major potential threat to people’s system security. Meltdown and Spectre Meltdown targeted Inte...

The vulnerabilities of Intel and ARM processors stem from the use of speculative execution and memory reading before returning addresses of previous write operations to memory. This allows attackers to exploit these vulnerabilities to disclose protected information.

The vulnerabilities of Intel and ARM processors are related to the use of speculative execution and memory reading before returning addresses of previous write operations to memory. Exploiting these vulnerabilities can allow attackers to disclose sensitive information through specially crafted...

DEBIAN-CVE-2019-7308

kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable out-of-bounds speculation on pointer arithmetic in various cases, including cases of different branches with different state or limits to sanitize, leading to side-channel attacks...

Security Bulletin: IBM Security QRadar Packet Capture is vulnerable to 3RD PARTY CPU hardware utilizing speculative execution cache timing side-channel analysis known as Variant 4 or SpectreNG (CVE-2018-3639, CVE-2018-3640)

Summary Speculative execution is a technique used by many modern processors to improve performance by predicting which instructions may be executed based on past execution history. An attacker with local user access may be able to utilize sequences of speculative execution to perform a cache timi...
