CVE-2019-18809 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the KVM implementation in the Linux kernel, when
paravirtual TLB flushes are enabled in guests, the hypervisor in some
situations could miss deferred TLB flushes or otherwise mishandle them. An
attacker in a guest VM could use this to expose sensitive information (read
memory from another guest VM). (CVE-2019-3016)
Paulo Bonzini discovered that the KVM hypervisor implementation in the
Linux kernel could improperly let a nested (level 2) guest access the
resources of a parent (level 1) guest in certain situations. An attacker
could use this to expose sensitive information. (CVE-2020-2732)
