CVE-2018-15572

Priority
Description
The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in
the Linux kernel before 4.18.1 does not always fill RSB upon a context
switch, which makes it easier for attackers to conduct userspace-userspace
spectreRSB attacks.
Ubuntu-Description
It was discovered that microprocessors utilizing speculative execution and
prediction of return addresses via Return Stack Buffer (RSB) may allow
unauthorized memory reads via sidechannel attacks. An attacker could use
this to expose sensitive information.
