CVE-2019-16233 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the QLogic Fibre Channel driver in the Linux kernel
did not properly check for error, leading to a NULL pointer dereference. A
local attacker could possibly use this to cause a denial of service (system
crash). (CVE-2019-16233)
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).
(CVE-2019-16234)
Tristan Madani discovered that the block I/O tracing implementation in the
Linux kernel contained a race condition. A local attacker could use this to
cause a denial of service (system crash) or possibly expose sensitive

use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-14895, CVE-2019-14901)
It was discovered that a heap-based buffer overflow existed in the Marvell

kernel: null pointer dereference in drivers/scsi/qla2xxx/qla_os.c
drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.
A flaw was found in the Linux kernel. A NULL pointer dereference flaw was found in the QLOGIC drivers for HBA. A call to alloc_workqueue return was not validated and can cause a denial of service. The highest threat from this vulnerability is to system availability.
Mitigation: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CVE-2019-16233 kernel: null pointer dereference in drivers/scsi/qla2xxx/qla_os.c
A NULL pointer dereference flaw was found in qla2x00_probe_one in drivers/scsi/qla2xxx/qla_os.c in Qlogic drivers for HBA. Here a call to alloc_workqueue return was not validated and this can cause a denial of service at the time of failure. This could allow an attacker to crash the system or leak kernel internal information.
