Description

linux, linux-lts-xenial, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities It was discovered that a race condition existed in the Precision Time Protocol (PTP) implementation in the Linux kernel, leading to a use-after- free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-10690) 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) Shijie Luo discovered that the ext4 file system implementation in the Linux kernel did not properly check for a too-large journal size. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a denial of service (soft lockup). (CVE-2020-8992)
