CVE-2016-2186

Status Candidate

Overview

Ubuntu Security Notice 2997-1 - Jann Horn discovered that eCryptfs improperly attempted to use the mmap() handler of a lower filesystem that did not implement one, causing a recursive page fault to occur. A local unprivileged attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. Ralf Spenneberg discovered that the USB sound subsystem in the Linux kernel did not properly validate USB device descriptors. An attacker with physical access could use this to cause a denial of service (system crash). Various other issues were also addressed.

Ubuntu Security Notice 2971-3 - Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in the Linux kernel did not properly sanity check the endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash). Zach Riggle discovered that the Linux kernel's list poison feature did not take into account the mmap_min_addr value. A local attacker could use this to bypass the kernel's poison-pointer protection mechanism while attempting to exploit an existing kernel vulnerability. Various other issues were also addressed.
