Overview

Affected versions of this package are vulnerable to Information Exposure due to not correctly mitigating SMT attacks, via a strange pattern in the kernel API using STIBP as a mitigation, leaving the process exposed for a short period of time after a syscall. The kernel also does not issue an IBPB immediately during the syscall.
