CWE-254  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.18.1 or higher.

Overview

Affected versions of this package are vulnerable to Security Features. 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.
