"details": "It was discovered that some Intel processors may not properly invalidate\ncache entries used by Intel Virtualization Technology for Directed I/O\n(VT-d). This may allow a local user to perform a privilege escalation\nattack. (CVE-2020-24489)\n\nJoseph Nuzman discovered that some Intel processors may not properly apply\nEIBRS mitigations (originally developed for CVE-2017-5715) and hence may\nallow unauthorized memory reads via sidechannel attacks. A local attacker\ncould use this to expose sensitive information, including kernel\nmemory. (CVE-2020-24511)\n\nTravis Downs discovered that some Intel processors did not properly flush\ncache-lines for trivial-data values. This may allow an unauthorized user to\ninfer the presence of these trivial-data-cache-lines via timing sidechannel\nattacks. A local attacker could use this to expose sensitive\ninformation. (CVE-2020-24512)\n\nIt was discovered that certain Intel Atom processors could expose memory\ncontents stored in microarchitectural buffers. A local attacker could use\nthis to expose sensitive information. (CVE-2020-24513)\n",
