This may allow a local user to perform a privilege escalation attack. (CVE-2021-24489) 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 21.04: intel-microcode 3.20210608.0ubuntu0.21.04.1 Ubuntu 20.10: intel-microcode 3.20210608.0ubuntu0.20.10.1 Ubuntu 20.04 LTS: intel-microcode 3.20210608.0ubuntu0.20.04.1 Ubuntu 18.04 LTS: intel-microcode 3.20210608.0ubuntu0.18.04.1 Ubuntu 16.04 ESM: intel-microcode 3.20210608.0ubuntu0.16.04.1+esm1 Ubuntu 14.04 ESM: intel-microcode 3.20210608.0ubuntu0.14.04.1+esm1 After a standard system update you need to reboot your computer to make all the necessary changes
