Summary

CVE-2022-4269

William Zhao discovered that a flaw in the Traffic Control (TC)
subsystem when using a specific networking configuration

(triggering a CPU soft lockup).

CVE-2022-39189

Jann Horn discovered that TLB flush operations are mishandled in

may allow an unprivileged guest user to compromise the guest
kernel.

CVE-2023-1206
