Threat Score
A critical Use-After-Free flaw in CentOS 9's sch_cake packet scheduler enables local privilege escalation to root; a public PoC demonstrating KASLR bypass, heap spraying and a ROP chain has been released and no vendor patch is yet available, so administrators should restrict access to tc or sch_cake module loading until fixed.
