Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the lack of verification of usernames during session matching. This vulnerability may allow the use of...

util-linux 安全漏洞

util-linux is an open-source software package. Versions of util-linux prior to 2.41.4 contained a security vulnerability. This vulnerability stemmed from a TOCTOU race condition in the SUID binary file mount, which could allow unauthorized access to files...

CVE-2026-27456

util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU Time-of-Check-Time-of-Use vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path with user privilege...

Important: mount-s3

Issue Overview: time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used...

EUVD-2026-17383

OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in the fs-bridge writeFile commit step that uses an unanchored container path during the final move operation. An attacker can exploit a time-of-check-time-of-use race condition by modifying parent paths inside the sandbox...

GHSA-XXJ4-96PH-G6J6 Duplicate Advisory: OpenClaw: Sandbox `writeFile` commit could race outside the validated path

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xvx8-77m6-gwg6. This link is maintained to preserve external references. Original Description OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in the fs-bridge writeFile commit step tha...

CVE-2026-32977 OpenClaw < 2026.3.11 - Sandbox Boundary Bypass via Unanchored writeFile Commit Path

OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability in the fs-bridge writeFile commit step that uses an unanchored container path during the final move operation. An attacker can exploit a time-of-check-time-of-use race condition by modifying parent paths inside the sandbox...

CVE-2026-32977

CVE-2026-32977 : OpenClaw before 2026.3.11 contains a sandbox boundary bypass in the fs-bridge writeFile commit step that uses an unanchored container path during the final move. A time-of-check–time-of-use race allows an attacker to modify parent paths inside the sandbox to redirect committed fi...

CVE-2026-33490

A flaw was found in H3, a minimal HTTP framework. The mount method, responsible for routing requests to sub-applications, incorrectly uses a simple string comparison to check path prefixes. This allows a remote attacker to craft a URL that bypasses the intended path segment boundary. Consequently...

CVE-2026-33490

H3 is a minimal HTTP framework. In versions 2.0.0-0 through 2.0.1-rc.16, the mount method in h3 uses a simple startsWith check to determine whether incoming requests fall under a mounted sub-application's path prefix. Because this check does not verify a path segment boundary i.e., that the next...

CVE-2026-33490 h3: Missing Path Segment Boundary Check in `mount()` Causes Middleware Execution on Unrelated Prefix-Matching Routes

CVE-2026-33490

Summary (CVE-2026-33490) : In h3 versions 2.0.0-0 through 2.0.1-rc.16, the mount() implementation uses a startsWith() path-prefix check without validating a segment boundary, allowing middleware registered on a mounted sub-app (e.g., at /admin) to run for unrelated routes such as /admin-public or...
