USN-6396-1 linux, linux-aws, linux-aws-hwe, linux-azure, linux-azure-4.15, linux-gcp, linux-gcp-4.15, linux-hwe, linux-oracle vulnerabilities

It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. CVE-2022-27672 Daniel Moghimi discovered that some IntelR Processors...

x86/AMD: Divide speculative information leak

ISSUE DESCRIPTION In the Zen1 microarchitecure, there is one divider in the pipeline which services uops from both threads. In the case of DE, the latched result from the previous DIV to execute will be forwarded speculatively. This is a covert channel that allows two threads to communicate witho...

USN-6385-1 linux-oem-6.0 vulnerabilities

It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. CVE-2022-27672 William Zhao discovered that the Traffic Control TC...
