Descriptions
A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042.
Una pérdida de memoria en la función crypto_report() en el archivo crypto/crypto_user_base.c en el kernel de Linux versiones hasta la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función crypto_report_alg(), también se conoce como CID-ffdde5932042.
A flaw was found in the Linux kernel. The crypto_report function mishandles resource cleanup on error. A local attacker able to induce the error conditions could use this flaw to crash the system. The highest threat from this vulnerability is to system availability.
