CVE-2025-24084 is a critical remote code execution vulnerability in the Windows Subsystem for Linux 2 kernel caused by dereference of an untrusted pointer. The flaw affects the WSL2 kernel component and arises from unsafe handling of attacker-controlled pointer data, which can lead to unintended memory access and execution of arbitrary code. Available reporting indicates the vulnerability may be reachable through specially crafted content delivered via email or another communication platform, and in the worst case exploitation may occur upon delivery alone without additional user interaction. The issue is described as allowing code execution by an unauthorized attacker and is associated with a CVSS base score of 8.4.
