| Revision Date: | 2017-04-19 | Version: | 1 | | Title: | CVE-2017-7979 on Ubuntu 16.04 LTS (xenial) - medium. | | Description: | The cookie feature in the packet action API implementation in net/sched/act_api.c in the Linux kernel 4.11.x through 4.11-rc7 mishandles the tb nlattr array, which allows local users to cause a denial of service (uninitialized memory access and refcount underflow, and system hang or crash) or possibly have unspecified other impact via "tc filter add" commands in certain contexts. NOTE: this does not affect stable kernels, such as 4.10.x, from kernel.org. Fabian Grünbichler discovered that the Packet action API implementation in the Linux kernel improperly handled uninitialized data. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
