CVE-2019-16234
Published: 11 September 2019
drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.
From the Ubuntu Security Team
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 (system crash).
