CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2017-18075 – kernel: Mishandled freeing of instances in pcrypt.c can allow a local user to cause a denial of service
https://notcve.org/view.php?id=CVE-2017-18075
crypto/pcrypt.c in the Linux kernel before 4.14.13 mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls. crypto/pcrypt.c en el kernel de Linux en versiones anteriores a la 4.14.13 gestiona de manera incorrecta la liberación de instancias, lo que permite que un usuario local acceda a la interfaz AEAD basada en AF_ALG (CONFIG_CRYPTO_USER_API_AEAD) y pcrypt (CONFIG_CRYPTO_PCRYPT) para provocar una denegación de servicio (kfree de un puntero incorrecto) o, posiblemente, causar otro tipo de impacto sin especificar mediante la ejecución de una secuencia manipulada de llamadas del sistema. crypto/pcrypt.c in the Linux kernel, before 4.14.13, mishandles freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls.

https://notcve.org/view.php?id=CVE-2018-1000004
In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition. En el kernel de Linux en versiones 4.12, 3.10, 2.6 y, probablemente, versiones anteriores, existe una vulnerabilidad en el sistema de sonido, lo que puede conducir a un deadlock y a una condición de denegación de servicio (DoS). In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service.
