CVE-2026-6844

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.

Summary		(es) Se encontró una falla en la utilidad ’readelf’ del paquete binutils. Un atacante local podría explotar dos vulnerabilidades de denegación de servicio (DoS) al proporcionar un archivo Executable and Linkable Format (ELF) especialmente diseñado. Una vulnerabilidad, un agotamiento de recursos (CWE-400), puede llevar a una condición de falta de memoria. La otra, una desreferencia de puntero nulo (CWE-476), puede causar una falla de segmentación. Ambos problemas pueden resultar en que la utilidad ’readelf’ deje de responder o se bloquee, lo que lleva a una denegación de servicio.
