CVE-2026-54001 Details
Description
osquery is a SQL powered operating system instrumentation, monitoring, and analytics framework. Prior to 5.23.1, on Windows, a local unprivileged attacker can cause a heap buffer out-of-bounds write if there is a query of the authenticode table targeting a maliciously crafted binary, due to publisher information parsing in getOriginalProgramName. If exploited successfully, this could allow a potential local privilege escalation from standard user to SYSTEM. This issue is fixed in version 5.23.1.
A heap buffer overflow vulnerability has been identified in osquery versions prior to 5.23.1 on Windows. This vulnerability allows a local unprivileged attacker to write outside the bounds of a heap buffer by crafting a malicious binary that exploits the publisher information parsing in the authenticode table. Successful exploitation could lead to local privilege escalation from a standard user to SYSTEM.
Users can upgrade to osquery version 5.23.1 or later to address this vulnerability. If an immediate upgrade is not possible, queries to the authenticode table can be disabled on Windows.
