It was discovered that some Intel processors may not properly invalidate
cache entries used by Intel Virtualization Technology for Directed I/O
(VT-d). This may allow a local user to perform a privilege escalation
attack. (CVE-2020-24489)
Joseph Nuzman discovered that some Intel processors may not properly apply
EIBRS mitigations (originally developed for CVE-2017-5715) and hence may
allow unauthorized memory reads via sidechannel attacks. A local attacker
could use this to expose sensitive information, including kernel
memory. (CVE-2020-24511)
Travis Downs discovered that some Intel processors did not properly flush
cache-lines for trivial-data values. This may allow an unauthorized user to
infer the presence of these trivial-data-cache-lines via timing sidechannel
attacks. A local attacker could use this to expose sensitive
information. (CVE-2020-24512)
It was discovered that certain Intel Atom processors could expose memory
contents stored in microarchitectural buffers. A local attacker could use
this to expose sensitive information. (CVE-2020-24513)
