CVE-2019-19062

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.

It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. It was discovered that a race condition existed in the Virtual Video Test Driver in the Linux kernel. An attacker with write access to /dev/video0 on a system with the vivid module loaded could possibly use this to gain administrative privileges. Various other issues were also addressed.
