Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.4.22 Description A time-of-check/time-of-use TOCTOU race condition exists in OpenShell sandbox filesystem writes. This flaw allows attackers to use symlink swaps during filesystem operations to bypass sandbox...

CVE-2026-31700

A flaw was found in the Linux kernel. A Time-of-check to Time-of-use TOCTOU race condition exists in the tpacketsnd function when PACKETVNETHDR is enabled. A local user can exploit this by modifying the vnethdr fields in the mmap'd TX ring buffer between validation and use, thereby bypassing safe...

CVE-2026-31700

In the Linux kernel, the following vulnerability has been resolved: net/packet: fix TOCTOU race on mmap'd vnethdr in tpacketsnd In tpacketsnd, when PACKETVNETHDR is enabled, vnethdr points directly into the mmap'd TX ring buffer shared with userspace. The kernel validates the header via...

CVE-2026-35364

A flaw was found in the mv utility of uutils coreutils. A local attacker with write access to a destination directory can exploit a Time-of-Check to Time-of-Use TOCTOU race condition during cross-device file operations. This allows the attacker to replace the intended destination with a symbolic...

CVE-2026-35354

A flaw was found in the mv utility of uutils coreutils. A local attacker with write access to a directory can exploit a Time-of-Check to Time-of-Use TOCTOU vulnerability during cross-device moves. This race condition allows the attacker to swap files between system calls, leading to the destinati...

Time-of-check Time-of-use

Spring Security is vulnerable to a Time-of-check Time-of-use race condition. The vulnerability is due to a Time-of-Check Time-of-Use TOCTOU issue in JdbcOneTimeTokenService, where token validation and usage are not performed atomically, allowing attackers to reuse or race token consumption and...

CVE-2026-41488

A flaw was found in langchain-openai. A remote attacker could exploit a Time-of-Check to Time-of-Use TOCTOU vulnerability, also known as a DNS rebinding vulnerability. This occurs because the urltosize helper, used for image token counting, validates URLs for Server-Side Request Forgery SSRF...

EUVD-2026-25635

LangChain is a framework for building agents and LLM-powered applications. Prior to 1.1.14, langchain-openai's urltosize helper used by getnumtokensfrommessages for image token counting validated URLs for SSRF protection and then fetched them in a separate network operation with independent DNS...

CVE-2026-35376

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the chcon utility of uutils coreutils during recursive operations.
