CVE-2018-9415
Published: 3 July 2018
In driver_override_store and driver_override_show of bus.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-69129004 References: Upstream kernel.
From the Ubuntu Security Team
It was discovered that a race condition existed in the ARM Advanced Microcontroller Bus Architecture (AMBA) driver in the Linux kernel that could result in a double free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

sbeattie | the fix to drivers/pci/pci-sysfs.c in the first patchwork link may be needed, too. |
