Summary: linux, linux-aws, linux-gcp, linux-gcp-5.3, linux-kvm, linux-oracle vulnerabilities

Details: Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-15794) 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 ARM Komeda display 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-2019-18810) It was discovered that the VirtualBox guest driver implementation in 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-2019-19048) 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, CVE-2019-19061) 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 AMD Audio Coprocessor driver for the Linux kernel did not properly deallocate memory in certain error conditions. A local attacker with the ability to load modules could use this to cause a denial of service (memory exhaustion). (CVE-2019-19067) It was discovered in the Qualcomm FastRPC 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-2019-19069) 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) It was discovered that the AMD Display Engine Driver in the Linux kernel did not properly deallocate memory in certain error conditions. A local attack could use this to cause a denial of service (memory exhaustion). (CVE-2019-19083) 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)
