CVE-2019-10220 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Michael Hanselmann discovered that the CIFS implementation in the Linux
kernel did not sanitize paths returned by an SMB server. An attacker
controlling an SMB server could use this to overwrite arbitrary files.
(CVE-2019-10220)
It was discovered that a heap-based buffer overflow existed in the Marvell
WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could
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

Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux
kernel did not properly handle reference counting during memory mapping
operations when used in conjunction with AUFS. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-15794)
Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel
did not properly validate SSID lengths. A physically proximate attacker
could use this to cause a denial of service (system crash).
