Description

linux, linux-aws, inux-azure, linux-gcp, linux-kvm, linux-oracle, linux-raspi, linux-riscv vulnerabilities It was discovered that the elf handling code in the Linux kernel did not initialize memory before using it in certain situations. A local attacker could use this to possibly expose sensitive information (kernel memory). (CVE-2020-10732) Matthew Sheets discovered that the SELinux network label handling implementation in the Linux kernel could be coerced into de-referencing a NULL pointer. A remote attacker could use this to cause a denial of service (system crash). (CVE-2020-10711) It was discovered that the SCSI generic (sg) driver in the Linux kernel did not properly handle certain error conditions correctly. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2020-12770) It was discovered that the USB Gadget device driver in the Linux kernel did not validate arguments passed from configfs in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2020-13143) It was discovered that the KVM implementation in the Linux kernel did not properly deallocate memory on initialization for some processors. A local attacker could possibly use this to cause a denial of service. (CVE-2020-12768)
