lockc

lockc is open source sofware for providing MAC Mandatory Access Control type of security audit for container workloads. The main reason why lockc exists is that containers do not contain. Containers are not as secure and isolated as VMs. By default, they expose a lot of information about host OS...

CVE-2021-3490

The eBPF ALU32 bounds tracking for bitwise ops AND, OR and XOR in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. Compile: gcc -o pwn pwn.c && gcc -o exploit exploit.c...

CVE-2017-16995

Linux Kernel Version 4.14 - 4.4 Ubuntu && Debian Description This vulnerability exists in the eBPF bpf2 system call in the Linux kernel. When a user provides a malicious BPF program that causes a calculation error in the eBPF verifier module, it leads to arbitrary memory read/write issues...

CVE-2026-98572

A flaw was found in the Linux kernel's extended Berkeley Packet Filter eBPF Just-In-Time JIT compiler on 32-bit MIPS systems. An instruction generation error during 64-bit jump comparisons causes negative numeric constants to be incorrectly evaluated against a hardware register instead of the...

Connection Escrow: Holding AI-Agent Pod Egress in the Kernel until an Isolated Verifier Rules

AI agents in containers act by opening network connections, and the text that drives them can be hostile. Controls placed between the agent and its tools are bypassed by a child process or a direct socket, and their approval is not tied to the connection the kernel later opens. We present...

CVE-2022-23222

CVE-2022-23222 Click here if you just wanna build and run the dang thing. What follows is more or less a translation of the Chinese writeup, available here. We'll use the mainline kernel code for version 5.13.0 as a reference. There is a mismatch in available pointer types and the function that...

6. CVE-2026-7878 – eBPF Verifier Type Confusion → Kernel Memory Read/Write Overview A subtle integer overflow in the eBPF verifier’s bounds tracking allows an attacker to craft an eBPF program that accesses out‑of‑bounds kernel memory. Severity: Critical Kernel Privilege Escalation User‑mode eBPF...

CVE-2026-48496

A flaw was found in OpenTelemetry eBPF Profiler. An unprivileged process can exploit this vulnerability by causing the profiler to open a nonregular mapping file, such as a FIFO First-In, First-Out, which leads to the profiler blocking indefinitely. This prevents further ELF Executable and Linkab...
