    @ajay9470 @caballerobrah Only if the eBPF checker is formally verified, because as of now...https://www.sentinelone.com/vulnerability-database/cve-2023-2163/ I am also not sure if an all eBPF kernel has the expressiveness needed, as programs are currently bounded computationally

    Post summary

    The tweet references CVE-2023-2163 but lacks substantive details, PoC, patch, or exploitation information, merely questioning the feasibility of an eBPF-based solution.
