sandboxec

sandboxec 基于 Landlock 的轻量级 Linux 命令沙箱。 无需守护进程。无需 root。无需镜像构建步骤。 用它来运行有风险的命令，缩小爆炸半径：第三方 CLI、不受信任的脚本、生成的代码以及一次性工具。 目的 运行不受信任的代码通常是全有或全无的选择。 容器和虚拟机是很好的工具，但对于快速的命令级隔离来说可能过于繁重。容器增加了镜像和运行时开销。虚拟机提供了更强的隔离性，但设置和资源成本更高。 sandboxec 专注于更狭窄的任务：在当前主机上沙箱化一个命令，开销低，并具有显式的允许规则。 另见 ： D.

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: “landlock”: Fixed the “dparent” walk. The WARNONONCE function in “collectdomainaccesses” can be triggered when trying to link a root mount point. This does not actually work in practice because this directory is already mounted,...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fscrypt: destroy keyring after securitysbdelete The function fscryptDestroykeyring must be called after all potentially-encrypted inodes have been evicted; otherwise, it cannot safely destroy the keyring. Since inodes that are...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Landlock: Do not lose track of restrictions on credtransfer. When a process’s credstruct is replaced, this mechanism almost always invokes the credprepare LSM hook. However, in one special case when KEYCTLSESSIONTOPARENT updates...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: samples/landlock: Fixed the memory leak in pathlist. Clang static analysis reports this error. sandboxer.c:134:8: Warning: Potential memory leak pointed to by ‘pathlist’. ret = 0; ^ pathlist is allocated in parsepath, but never...

Linux Distros Unpatched Vulnerability : CVE-2026-72183

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - landlock: Fix LANDLOCKSCOPESIGNAL bypass on the SIGIO path LANDLOCKSCOPESIGNAL must prevent a sandboxed process from signaling processes outside its Landlock...

CVE-2026-72183

A flaw was found in the Linux kernel's Landlock security module. A sandboxed process can bypass the intended signal isolation provided by LANDLOCKSCOPESIGNAL. By manipulating file descriptors with specific fcntl calls and asynchronous I/O SIGIO delivery, a local attacker can send signals, such as...

It can be bypassed through the asynchronous SIGIO delivery path...

CVE-2026-72183

CVE-2026-72183 concerns a Linux kernel LANDLOCK bypass on the SIGIO path. The vulnerability allowed a sandboxed process that owns a file/socket to arm fcntl(F_SETOWN), F_SETSIG and O_ASYNC so that an I/O event would deliver a chosen signal to the entire process group, potentially affecting non-sa...

PYSEC-2026-3504 PraisonAI SandlockSandbox falls back to unrestricted subprocess execution when Landlock is unavailable

Summary praisonai.sandbox.SandlockSandbox is documented and implemented as the kernel-enforced sandbox backend for untrusted code. Its SandboxConfig.native path lets callers configure allowed filesystem paths and network=False. On systems where the optional sandlock module imports but reports tha...

CVE-2026-47128 nono: Sandbox escape on Linux via D-Bus: `systemd-run --user`

nono is software that allows users to run AI agents in a zero-latency sandbox. Prior to version 0.55.0, the nono Landlock/seccomp policies allow access to local Unix domain sockets concrete and abstract. This allows an easy sandbox escape by talking to the per-user systemd dbus socket. Version...

GHSA-72W7-MF9G-733P nono-py has proxy-only network fallback bypass on older Linux kernels

Summary On Linux kernels that do not support Landlock network rules, nonopy.sandboxedexec could run CapabilitySet.proxyonlyproxy without supervising the seccomp-notify proxy-only fallback returned by the Rust core. In that configuration, a sandboxed child process could remove HTTPPROXY / HTTPSPRO...
