New SWAPGS Side-Channel Attack Bypasses Spectre and Meltdown Defenses

[silversurfer]

Researchers demonstrate a new side-channel attack that bypass mitigations against Spectre and Meltdown.
 
Millions of newer Intel microprocessors manufactured after 2012 are vulnerable to a new type of side-channel attack dubbed SWAPGS.
 
SWAPGS is similar to existing side-channel attacks such as Spectre and Meltdown and similarly could allow a hacker to gain access to sensitive data such as passwords and encryption keys on consumer and enterprise PCs.
 
“This newly disclosed attack bypasses all known mitigation mechanisms implemented in response to Spectre and Meltdown,” wrote security researchers at Bitdefender that discovered the flaw and developed a way of exploiting it in Intel chips.
