b217f9accfba4a764bd6f85c953f7739d90f11d6b6ba34b105c6fadfa4adafeeIt 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 could use this to expose sensitive information (memory from the kernel or other processes). It was discovered that the paravirtualization implementation in the Linux kernel did not properly handle some indirect calls, reducing the effectiveness of Spectre v2 mitigations for paravirtual guests. A local attacker could use this to expose sensitive information. Various other issues were also addressed.

This vulnerability is also known as L1 Terminal Fault. A local attacker in a guest virtual machine could use this to expose sensitive information. Jann Horn and Ken Johnson discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via a sidechannel attack. This flaw is known as Spectre Variant 4. A local attacker could use this to expose sensitive information, including kernel memory. Various other issues were also addressed.

05614d3f47ad2de76096fa4834b1c267cdc304f39da1abf393a87b454245c715FreeBSD Security Advisory - On certain Intel 64-bit x86 systems there is a period of time during terminal fault handling where the CPU may use speculative execution to try to load data. The CPU may speculatively access the level 1 data cache (L1D). Data which would otherwise be protected may then be determined by using side channel methods. This issue affects bhyve on FreeBSD/amd64 systems. An attacker executing user code, or kernel code inside of a virtual machine, may be able to read secret data from the kernel or from another virtual machine.
