In a recent post by ZDI, researchers found an out-of-bounds access flaw (CVE-2021-31440) in the Linux kernel’s (5.11.15) implementation of the eBPF code verifier: an incorrect register bounds calculation occurs while checking unsigned 32-bit instructions in an eBPF program. The flaw can be leveraged to escalate privileges and execute arbitrary code in the context of the kernel.
Ideally, observability should help you understand the state of your application and how it performs under different circumstances. However, while serverless observability may seem similar to serverless monitoring and testing, the three achieve different goals. Testing helps you check your application for known issues, and monitoring helps you evaluate system health according to known metrics. Observability helps you search and discover unknown issues, providing end-to-end visibility.
