USN-4210-1: Linux kernel vulnerabilities


Severity

Medium

Vendor

Canonical Ubuntu

Versions Affected
  • Canonical Ubuntu 16.04
Description

It was discovered that a buffer overflow existed in the 802.11 Wi-Fi configuration interface for the Linux kernel when handling beacon settings. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-16746)

Nicolas Waisman discovered that the WiFi driver stack in the Linux kernel did not properly validate SSID lengths. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-17133)

It was discovered that the ADIS16400 IIO IMU Driver for the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19060)

It was discovered that the Intel OPA Gen1 Infiniband Driver for the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19065)

It was discovered that the Cascoda CA8210 SPI 802.15.4 wireless controller driver for the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2019-19075)

Nicolas Waisman discovered that the Chelsio T4/T5 RDMA Driver for the Linux kernel performed DMA from a kernel stack. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-17075)

CVEs contained in this USN include: CVE-2019-16746, CVE-2019-17075, CVE-2019-17133, CVE-2019-19060, CVE-2019-19065, CVE-2019-19075
