kernel: Spectre v2 SMT mitigations problem

It was found that the Linux Kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The kernel failed to protect applications that attempted to protect against Spectre v2 leaving them open to attack from other processes...

kernel: AMD: Cross-Thread Return Address Predictions

A flaw was found in HW. When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch, potentially resulting in information disclosure...

The vulnerability of AMD’s SMT processor technology, which allows a hacker to disclose protected information

The vulnerability of AMD’s SMT processor technology is related to errors that occur after the processor’s core exits the C0 sleep state. Exploiting this vulnerability can allow an attacker to disclose protected information i.e., gain access to the RAP Return Address Predictor...
