CVE-2018-15594

Priority
Description
arch/x86/kernel/paravirt.c in the Linux kernel before 4.18.1 mishandles
certain indirect calls, which makes it easier for attackers to conduct
Spectre-v2 attacks against paravirtual guests.
Ubuntu-Description
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.
