CVE-2026-6844
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Summary
A flaw was found in the readelf utility of the binutils package. A local attacker could exploit two Denial of Service (DoS) vulnerabilities by providing a specially crafted Executable and Linkable Format (ELF) file. One vulnerability, a resource exhaustion (CWE-400), can lead to an out-of-memory condition. The other, a null pointer dereference (CWE-476), can cause a segmentation fault. Both issues can result in the readelf utility becoming unresponsive or crashing, leading to a denial of service.

Workarounds
To mitigate this vulnerability, users should avoid using the readelf utility on untrusted or suspicious ELF files. Processing a specially crafted ELF file with readelf can lead to a denial of service.
