CVE-2019-16234

El archivo drivers/net/wireless/intel/iwlwifi/pcie/trans.c en el kernel de Linux versión 5.2.14, no comprueba el valor de retorno en alloc_workqueue, conllevando a una desreferencia del puntero NULL.

A flaw was found in the Linux kernel. A check was not done on the alloc_workqueue return value of the iwl_trans_pcie_alloc function potentially leading to a NULL pointer dereference. This error condition could lead to a denial of service. The highest threat from this vulnerability is to system availability.

Al Viro discovered that the Linux kernel for s390x systems did not properly perform page table upgrades for kernel sections that use secondary address mode. A local attacker could use this to cause a denial of service or execute arbitrary code. It was discovered that the Intel Wi-Fi driver in the Linux kernel did not properly check for errors in some situations. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.
