Linux kernel vulnerabilities

Description

## Releases * Ubuntu 12.04 ## Packages * linux \- Linux kernel Andrey Konovalov discovered that the CDC Network Control Model USB driver in the Linux kernel did not cancel work events queued if a later error occurred, resulting in a use-after-free. An attacker with physical access could use this to cause a denial of service (system crash). (CVE-2016-3951) Kangjie Lu discovered an information leak in the core USB implementation in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4482) Jann Horn discovered that the InfiniBand interfaces within the Linux kernel could be coerced into overwriting kernel memory. A local unprivileged attacker could use this to possibly gain administrative privileges on systems where InifiniBand related kernel modules are loaded. (CVE-2016-4565) Kangjie Lu discovered an information leak in the timer handling implementation in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4569, CVE-2016-4578) Kangjie Lu discovered an information leak in the X.25 Call Request handling in the Linux kernel. A local attacker could use this to obtain potentially sensitive information from kernel memory. (CVE-2016-4580) Baozeng Ding discovered a use-after-free issue in the generic PPP layer in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-4805) It was discovered that an information leak exists in the Rock Ridge implementation in the Linux kernel. A local attacker who is able to mount a malicious iso9660 file system image could exploit this flaw to obtain potentially sensitive information from kernel memory. (CVE-2016-4913)
