Description

linux-gke-5.0, linux-oem-osp1 vulnerabilities Tristan Madani discovered that the file locking implementation in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service or expose sensitive information. (CVE-2019-19769) It was discovered that the Serial CAN interface driver in the Linux kernel did not properly initialize data. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2020-11494) It was discovered that the linux kernel did not properly validate certain mount options to the tmpfs virtual memory file system. A local attacker with the ability to specify mount options could use this to cause a denial of service (system crash). (CVE-2020-11565) It was discovered that the OV51x USB Camera device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-11608) It was discovered that the STV06XX USB Camera device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-11609) It was discovered that the Xirlink C-It USB Camera device driver in the Linux kernel did not properly validate device metadata. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2020-11668) David Gibson discovered that the Linux kernel on Power9 CPUs did not properly save and restore Authority Mask registers state in some situations. A local attacker in a guest VM could use this to cause a denial of service (host system crash). (CVE-2020-11669) It was discovered that the block layer in the Linux kernel contained a race condition leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2020-12657)
