USN-3823-1: Linux kernel vulnerabilities linux vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 12.04 ESM Summary Several security issues were mitigated in the Linux kernel. Software Description linux – Linux kernel Details It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS). (CVE-2018-3646) It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault [ more… ]
