Descriptions
The blkcg_init_queue function in block/blk-cgroup.c in the Linux kernel before 4.11 allows local users to cause a denial of service (double free) or possibly have unspecified other impact by triggering a creation failure.
La función blkcg_init_queue en block/blk-cgroup.c en el kernel de Linux, en versiones anteriores a la 4.11, permite que los usuarios locales provoquen una denegación de servicio (doble liberación) o, posiblemente, causen otros impactos no especificados desencadenando un fallo de creación.
USN-3654-1 fixed vulnerabilities and added mitigations in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Jann Horn and Ken Johnson discovered that microprocessors utilizing speculative execution of a memory read may allow unauthorized memory reads via a sidechannel attack. This flaw is known as Spectre Variant 4. A local attacker could use this to expose sensitive information, including kernel memory. Various other issues were also addressed.
