What is CVE-2026-6844?

A flaw exists in the readelf utility of the binutils package that can be exploited by local attackers using specially crafted Executable and Linkable Format (ELF) files. One issue relates to resource exhaustion, which can cause an out-of-memory condition, while the other involves a null pointer dereference that may result in a segmentation fault. Both vulnerabilities may lead to the readelf utility becoming unresponsive or crashing, resulting in Denial of Service scenarios.
