Insight

Insight

Michael Hanselmann discovered that the CIFS implementation in the Linux kernel did not sanitize paths returned by an SMB server. An attacker controlling an SMB server could use this to overwrite arbitrary files. (CVE-2019-10220) It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895, CVE-2019-14901) It was discovered that a heap-based buffer overflow existed in the Marvell Libertas WLAN Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14896, CVE-2019-14897) It was discovered that the Fujitsu ES network device driver for the Linux kernel did not properly check for errors in some situations, leading to a NULL pointer dereference. A local attacker could use this to cause a denial of service. (CVE-2019-16231) It was discovered that the QLogic Fibre Channel driver in the Linux kernel did not properly check for error, leading to a NULL pointer dereference. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2019-16233) 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) Anthony Steinhauser discovered that the Linux kernel did not properly perform Spectre_RSB mitigations to all processors for PowerPC architecture systems in some situations. A local attacker could use this to expose sensitive information. (CVE-2019-18660) It was discovered that the Mellanox Technologies Innova driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A local attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19045) 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 Geschwister Schneider USB CAN interface driver in the Linux kernel did not properly deallocate memory in certain failure conditions. A physically proximate attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2019-19052) It was discovered that the netlink-based 802.11 configuration interface ...
