CVE-2024-31142: x86: Incorrect logic for BTC/SRSO mitigations
First published: Tue Apr 09 2024(Updated: )
Because of a logical error in XSA-407 (Branch Type Confusion), the mitigation is not applied properly when it is intended to be used. XSA-434 (Speculative Return Stack Overflow) uses the same infrastructure, so is equally impacted.
